Mike Elizalde of Spectral Motion applies make-up to actor Ron Perlman, as Hellboy.

Many of today's most original and bizarre visions of alternative worlds and landscapes come from the workshops of Hollywood effects studios. Behind the scenes of nondescript San Fernando Valley offices and warehouse spaces (if not outside California altogether, in the many other nodes of the ever-expanding global network of cinematic effects production, from suburban London to Wellington, New Zealand), lurk the multidisciplinary teams whose job it is to create tomorrow's monsters.

Spectral Motion, the effects house responsible for some of the most technically intricate and physically stunning animatronic creatures seen in feature film today, is no exception. Based in a small strip of anonymous one-story warehouse spaces squeezed in between a freeway and rail tracks, and overshadowed by a gargantuan Home Depot, Spectral Motion has developed monsters, effects, and other mechanical grotesqueries that have since become household nightmares, if not names.

Since its founding, by Mike & Mary Elizalde in 1994, the firm has worked on such films as Hellboy & Hellboy II: The Golden Army, Looper, Attack the Block, Blade 2 & Blade: Trinity, X-Men: First Class, The Watch, and this summer's (from the perspective of at least half of Venue) highly anticipated Pacific Rim.

Venue caught up with Mike Elizalde, CEO of Spectral Motion, on a cloudy day in Glendale to talk all things monstrous and disturbing. Our conversation ranged from the fine line that separates the grotesque and the alien to the possibility of planetary-scale creatures made using tweaked geotextiles, via the price of yak hair and John Carpenter's now-legendary Antarctic thriller, The Thing.



Elizalde, a good-humored conversationalist, not only patiently answered our many questions—with a head cold, no less—but then took us on a tour through Spectral Motion's surprisingly large workshop. We saw miniature zombie heads emerging from latex molds (destined for a film project by Elizalde's own son), costumes being sewn by a technician named Claire Flewin for an upcoming attraction at Disneyland, and a bewildering variety of body parts—heads, torsos, claws, and even a very hairy rubber chest once worn by Vinnie Jones in X-Men: The Last Stand—that were either awaiting, or had already performed, their celluloid magic.



The visit ended with a screening of Spectral Motion's greatest hits, so to speak, with in-house photographer and archivist Kevin McTurk—a chance to see the company's creations in their natural habitat. We walked back out into the flat light and beige parking lots of the Valley, a landscape enlivened by our heightened sense of the combination of close observation and inspired distortion required to transform the everyday into the grotesque.

Geoff Manaugh: I’d love to start with the most basic question of all: how would you describe Spectral Motion and what the company does?

Mike Elizalde: We are principally a prosthetics, animatronics, and special effects creature studio, but we are also a multifaceted design studio. We do a lot of different kinds of work. Most recently, for example, in partnership with one of my long-time colleagues, Mark Setrakian, we built anthropomorphic bipedal hydraulic robots that engage in battle, for a reality show for Syfy. It’s called RCLRobot Combat League. It’s pretty astounding what these machines can do, including what they can do to each other.

Battling it out in Robot Combat League with two robots—"eight-feet tall, state-of-the-art humanoid robots controlled by human 'robo-jockeys,'" in the words of Syfy—designed by Mark Setrakian of Spectral Motion.

Nicola Twilley: Are the robot battles choreographed, or do you genuinely not know which robot will win?

Elizalde: Oh, no, absolutely—it’s a contest. It really is about which robot will emerge as the victorious contender.

RCL is not only one of our most recent projects, but it also shows that, here at the studio, we can do everything from a very delicate prosthetic application on an actor, to an animatronic character in a film, to something that’s completely out of our comfort zone—like building battling robots.

I always tell people that, if they come in here with a drawing of a car, we could build that car. It is a very diverse group that we work with: artists, technicians, and, of course, we use all the available or cutting-edge technologies out there in the world to realize whatever it is that we are required to make.



Manaugh: What kind of design briefs come to you? Also, when a client comes to you, typically how detailed or amorphous is their request?

Elizalde: Sometimes it is very vague. But, typically, what happens is we’re approached with a script for a project. Our job is to go through the script and create a breakdown and, ultimately, a budget based on those breakdowns. We take whatever we think we should build for that script and we make suggestions as to how each thing should look—what should move, what the design should be, and so on.

Other times, we’ll be working with a director who’s very involved and who maybe even has some technical knowledge of what we do—especially someone like Guillermo del Toro. He’s completely savvy about what we do because he used to own a creature shop of his own, so working with someone like him is much more collaborative; he comes to us with a much more clear idea of what he wants to see in his films. Lots of times, he’ll even show us an illustration he’s done. He’s the first one to say, “I'm not an artist!” But he really is. He’s quite gifted.

So he’ll bring us his illustrations and say, you know, “You tell me if it’s going to be a puppet, an animatronic puppet, or a creature suit that an actor can wear.” And that’s where our knowhow comes in. That’s how it evolves.

There are also times—with the robot show, for example—where they know exactly what they need but they don’t know how to achieve it. In those cases, they come to us to do that for them.

Twilley: Can you talk us through one of the projects you’ve worked on where you had to create your vision based solely on what’s in the script, rather than more collaborative work with the director? What’s that process like?

Elizalde: Well, I’d actually say that ninety percent of our work is that way. For most of the projects we work on, we do, in fact, just get a script and the director says, “Show me what this looks like.” But we love that challenge. It’s really fun for us to get into the artistic side of developing what the appearance of something will end up looking like.

We had a lot of fun working with a director named Tommy Wirkola, for example, who directed Hansel & Gretel: Witch Hunters. He was the director of Dead Snow, a really strange Norwegian film that involved this group of young kids who go off to a cabin where they’re hunted down by a hoard of horrifying zombie Nazi monsters. It’s really grisly.

Anyway, although Tommy did have really good ideas about what he wanted his characters to look like for Hansel & Gretel, there were certain characters whose descriptions were much more vague—also because there was such a broad scope of characters in the film. So they did rely on us to come up with a lot of different looks based on loose descriptions. In the end, the principal characters in the film were total collaborations between Tommy, myself, and Kevin Messick, the producer, and the rest of my team here at Spectral Motion, of course.

I’d say that’s a good example of both worlds, where you have some clear ideas about a few characters, but, for another group of characters, there really isn’t a whole lot of information or a detailed description. You have to fill in a lot of blanks.

Twilley: What kinds of things do you look for in a script to give you a clue about how a character might work—or is that something that simply comes out when you’re sketching or modeling?

Elizalde: In a script, we basically know what we’re looking for: “Enter a monster.” We know that’s what we’re going be doing, so we look for those moments in the script. Sometimes there’s a brief description—something like, “the monster’s leathery hide covered in tentacles.” That kind of stuff gives us an immediate visual as to what we want to create. Then we explore it with both two-dimensional artwork and three-dimensional artwork, and both digital and physical.

In fact [gestures at desk], these are some examples of two-dimensional artwork that we’ve created to show what a character will look like. This [points to statuette above desk] is a maquette for one of the characters in Hellboy II—the Angel of Death. This was realized at this scale so that del Toro could see it and say, “That’s it. That’s what I want. Build that.” This actually began as an illustration that Guillermo did in his sketchbook, a very meticulous and beautiful illustration that he came to us with.

The Angel of Death from Hellboy II: The Golden Army.

But that’s the process: illustration and then maquette. Sometimes, though, we’ll do a 3D illustration in the computer before we go to the next stage, just to be able to look at something virtually, in three dimensions, and to examine it a little bit more before we invest the energy into creating a full-blown maquette.

The maquette, as a tool, can be very essential for us, because it allows us to work out any bugs that might be happening on a larger scale, design-wise. Practically speaking, it doesn’t give us a lot of information as to how the wings are going to work, or how it’s going to function; but it does tell us that a human being could actually be inside of it and that it could actually work as a full-scale creature. It’s essential for those reasons.

Because you can show a director a drawing, and it might look really terrific—but, when it comes to actually making it, in a practical application at scale, sometimes the drawing just doesn’t translate. Sometimes you need the maquette to help describe what the finished piece will look like.

Manaugh: You mentioned animatronics and puppeteering. We were just up at the Jet Propulsion Lab in Pasadena yesterday afternoon, talking to them about how they program certain amounts of autonomy into their instruments, especially if it’s something that they’re putting on Mars. It has to be able to act on its own, at times, because it doesn’t have enough time to wait for the command signal from us back on Earth. I’m curious, especially with something like the robot combat show, how much autonomy you can build into a piece. Can you create something that you just switch on and let go, so that it functions as a kind of autonomous or even artificially intelligent film prop?

Elizalde: It really depends on the application. For example, when we’re filming something, a lot of times there’s a spontaneity that’s required. Sometimes actors like to ad lib a little bit. If we need to react to something that an actor is saying via a puppet—an animatronic puppet—then that live performance really is required. But we always have the option of going to a programmable setup, one where we can have a specific set of parameters, performance-wise, to create a specific scene.

For live performances on a stage, we’d probably want to program that with the ability to switch over to manual, if required. But, if it’s scripted—if it’s a beat-by-beat performance—then we know that can be programmable. We can turn on the switch and let it go. In the middle of that, you can then stop it, and have a live show, with puppeteers in the background filling in the blanks of whatever that performance is, and then you can continue with the recorded or programmed performance.

It really goes back and forth, depending on what it is the people who are putting on the production need.

Twilley: That’s an interesting point—the idea of how a live actor responds to your creatures. Have there been any surprises in how an actor has responded, or do they all tend to know what they’re getting into by the time you’re filming?

Elizalde: They do know what they’re getting into, but it’s always rewarding to have an actor go over to the thing that you built, and stare at it, and say, “Oh, my God! Look at that thing!” They can feed off of that. I think they are able to create a more layered performance, with a lot more depth in their reactions to something if it’s actually there—if it’s present, if it has life to it, and it’s tactile.

A lot of times people turn to digital solutions. That’s also good, if the application is correct. But, you know, a lot of directors that we talk to are of the mind that a practical effect is far better for exactly that reason—because the actor does have a co-actor to work with, to play off of, and to have feelings about.

That’s one of the things that keeps us going. And, the fact is, with this business, no matter what walks through that door we know that it’s going to be a completely different set of challenges from the last thing that we did.

Manaugh: About six years ago, I interviewed a guy who did concept art for the Star Wars prequels, and he had a kind of pet obsession with building upside-down skyscrapers—that is, skyscrapers that grew downwards like stalactites. He kept trying to get them into a movie. He would build all of these amazing 3D models and show them to the director, and the director was always excited—but then he’d turn the model upside-down and say, “Let’s do it like this!” So all the upside-down skyscrapers would just be right-side up again. In any case, this artist was then working on the recent Star Trek reboot, and there’s a brief moment where you see upside-down skyscrapers on the planet Vulcan. It's only on screen for about a second and a half, but he finally did it—he got his upside-down skyscrapers into a film.

Elizalde: [laughs] But, ohhh! For half-a-second! [laughter]

Manaugh: Exactly. Anyway, in the context of what you do here at Spectral Motion, I’m curious if there is something like that, that you’ve been trying to get into a movie for the last few years but that just never quite makes it. A specific monster, or a new material, or even a particular way of moving, that keeps getting rejected.

Elizalde: That’s an interesting question. [pauses] You know, I’d have to say no. I’d say it seems like the more freely we think, the better the result is. So it’s quite the contrary: most of the stuff we suggest actually does make it into the film, because it’s something that someone else didn’t think about. Or perhaps we’ve added some movement to a character, or we’ve brought something that will elicit a more visceral reaction from the audience—bubbly skin, for instance, or cilia that wiggle around.

I don't think I’ve really encountered a situation where I thought something would look great, but, when I brought it to a director, they said, “Nah—I don’t think that’s going to go. Let's not try that.” They always seem to say, “Let’s try it! It sounds cool!”

Mike Elizalde applies some last-minute touch-ups to actor Ron Perlman on the set of Hellboy.

We really haven’t had a whole lot of frustration—maybe only when it turns into a very large committee making a decision on the film. Then, I suppose, a certain degree of frustration is more typical. But that happens in every industry, not just ours: the more people are involved in deciding something, the more difficult it is to get a clear image of what it is we’re supposed to do.

Manaugh: When we first spoke to set-up this interview, I mentioned that we’d be touring the landfill over at Puente Hills this morning, on our way here to meet you—it’s the biggest active landfill in the United States. What’s interesting is that it’s not only absolutely massive, it’s also semi-robotic, in the sense that the entire facility—the entire landscape—is a kind of mechanical device made from methane vents and sensors and geotextiles, and it grows everyday by what they call a “cell.” A “cell” is one square-acre, compacted twenty feet deep with trash. Everyday!

But I mention this because, during our visit there, I almost had the feeling of standing on top of a mountain-sized creature designed by Spectral Motion—a strange, half-living, half-mechanical monstrosity in the heart of the city, growing new “cells” every day of its existence. It’s like something out of Hellboy II. So I’m curious about the possibilities of a kind of landscape-scale creature—how big these things can get before you need to rely on CGI. Is it possible to go up to that scale, or what are the technical or budgetary limitations?



Elizalde: We can’t build mountains yet but, absolutely, we can go way up in scale! Many times, of course, we have to rely, at least to some degree, on digital effects—but that just makes our job easier, by extending what is possible, practically, and completing it cinematically, on screen, at a much larger scale.

For example, on Pacific Rim, Guillermo del Toro’s new film that comes out this summer, we designed what are called Jaegers. They’re basically just giant robots. And we also designed the Kaiju, the monsters in the film. First, we created maquettes, just like the ones here, and we made several versions of each to reflect the final designs you’ll see in the film. Those were taken and re-created digitally so they could be realized at a much larger scale.

To that degree, we can create something enormous. There’s a maquette around here somewhere of a character we designed for the first Hellboy movie—actually, there are two of them. One of those characters is massive—about the size of a ten-story building—and the other one is much, much bigger. It’s the size of… I don't know, a small asteroid. There really is no limit to the scale, provided we can rely on a visual effects company to help us realize our ultimate goal.

But going the opposite direction, scale-wise, is also something that interests us. We can make something incredibly tiny, depending on what the film requires. There is no limit in one direction or the other as to what can be achieved, especially with the power of extension through digital effects.

Manaugh: Just to continue, briefly, with the Puente Hills reference, something that we’ve been interested in for the past few years is the design of geotextiles, where companies like TenCate in the Netherlands are producing what are, effectively, landscape-scale blankets made from high-quality mesh, used to stabilize levees or to add support to the sides of landfills. But some of these geotextiles are even now getting electromagnetic sensors embedded in them, and there’s even the possibility of a geotextile someday being given mechanical motion—so it’s just fascinating, I think, to imagine what you guys could do with a kind of monstrous or demonic geotextile, as if the surface of the earth could rise up as a monster in Hellboy III.

Elizalde: [laughs] Well, now that I know about it, I’ll start looking into it!




Twilley: Aside from scale, we’re also curious about the nature of monsters in general. This is a pretty huge question, but what is a monster? What makes something monstrous or grotesque? There seems to be such a fine line between something that is alien—and thus frightening—and something that is so alienating it’s basically unrecognizable, and thus not threatening at all.

Elizalde: Exactly. Right, right.

Twilley: So how do you find that sweet spot—and, also, how has that sweet spot changed over time, at least since you’ve been in the business? Are new things becoming monstrous?

Elizalde: Well, I think my definition of a monster is simply a distortion: something that maybe looks close to a human being, for example, but there’s something wrong. It can be something slight, something subtle—like an eye that’s just slightly out of place—that makes a monster. Even a little, disturbing thing like that can frighten you.

So it doesn’t take a lot to push things to the limit of what I would consider the grotesque or the monstrous. At that point, it runs the gamut from the most bizarre and unimaginable things that you might read in an H. P. Lovecraft story to something simple, like a tarantula with a human head. Now there’s something to make me scream! I think there’s a very broad range. But you’re right: it’s a huge question.

And sometimes the monstrous defies definition. I guess it’s more of a primal reaction—something you can’t quite put your finger on or describe, but something that makes you feel uneasy. It makes you feel uncomfortable or frightened. A distortion of what is natural, or what you perceive as natural, something outside what you think is the order of things—or outside what you think is acceptable within what we’ve come to recognize as natural things—then that’s a monster. That’s a monstrous thing.

Do you recall seeing John Carpenter’s The Thing?

Manaugh: It's one of my favorite movies.

Elizalde: My goodness, the stuff in that film is the stuff of nightmares. It really is brilliantly executed, and it’s a great inspiration to all of the people in our industry who love monsters, and to all the fans all over the world who love monstrous things.

Twilley: Have there been trends over time? In other words, do you find directors look for a particular kind of monster at a particular moment in time?

Elizalde: I do think there are trends—although I think it’s mainly that there’s a tendency here in Hollywood where somebody hears a rumor that someone down the street is building a film around this particular creature, so that guy’s now got to write a similar script to compete. But sometimes the trends are set by something groundbreaking, like The Thing. Once that movie was released, everybody paid attention and a whole new area of exploration became available to create amazing moments in cinema.

Those are the real trends, you know. It’s a symbiosis that happens between the artistic community and the technological community, and it’s how it keeps advancing. It’s how it keeps growing. And it keeps us excited about what we do. We feed off of each other.

Technician Claire Flewin uses her hand to demonstrate how yak hair looks stretched over a mold.

Manaugh: Speaking of that symbiosis, every once in a while, you’ll see articles in a magazine like New Scientist or you’ll read a press release coming out of a school like Harvard, saying that they’ve developed, for instance, little soft robots or other transformable, remote-control creatures for post-disaster reconnaissance—things like that. I mention this because I could imagine that you might have multiple reactions to something like that: one reaction might be excitement—excitement to discover a new material or a new technique that you could bring into a film someday—but the other reaction might be something almost more like, “Huh. We did that ten years ago.” I’m curious as to whether you feel, because of the nature of the movies that you work on, that the technical innovations you come up with don’t get the attention or professional recognition that they deserve.

Elizalde: I think your assessment is accurate on both counts. There are times when we see an innovation, or a scientific development, that we think could be beneficial to our industry; in fact, that happens all the time. There’s cross-pollination like that going on constantly, where we borrow from other industries. We borrow from the medical industry. We borrow from the aerospace industry. We borrow, really, from whatever scientific developments there are out there. We seek them out and we do employ some of those methods in our own routines and systems.

In fact, one of our main designers, and a very dear friend of mine whom I’ve worked side by side with for years now, is Mark Setrakian. When he’s not working here with us, he is a designer at one of the labs you just described.

So there is a lot of crossover there.

The mechanical skull of the scrunt from Lady in the Water.

Manaugh: That’s interesting—do the people who work for you tend to come from scientific or engineering backgrounds, like Mark, or are they more often from arts schools? What kinds of backgrounds do they tend to have?

Elizalde: Generally speaking, I think they’re people like myself who just have a love for monsters. That’s honestly where a lot of people in our industry come from. There are people who started their careers as dental technicians and people who started out as mold-makers in a foundry. In all of those cases, people from those sorts of technical fields gravitate toward this work because of, first of all, a love for monsters and creatures, and, secondly, a technical ability that isn’t necessarily described as an art form per se. Electronics people love to work for us. People who design algorithms love to work for us. Even people with a background in dentistry, like I say, love to work for us.

There’s really no limit to the fields that bring people to this industry—they come from everywhere. The common thread is that we all love movies and we all love creatures. We love making rubber monsters for a living.

The shelves at Spectral Motion gives a good sense of the workshop's range of reference. Highlights include the Third Edition of the Atlas of Clinical Dermatology (in color), The National Audubon Society: Speaking for Nature, Marvel's Fantastic Four, The Graphic Works of Odilon Redon, and a Treasury of Fantastic and Mythological Creatures.

To go back to your previous question, there are definitely times when I think we don’t get a lot of exposure for what we do, but there is also, at some level, a kind of “don’t pay attention to the man behind the curtain” thing going on, where we don’t really want people to look backstage at what makes a movie work. We are creating a living creature for film, and that’s what we want to put across to the audience. In some ways, it’s actually better if there isn’t too much exposure as to how something was created; it’s like exposing a magic trick. Once you know the secret, it’s not that big a deal.

So we do live in a little bit of a shroud of secrecy—but that’s okay. After a film is released, it’s not unusual for more of what we did on that film to be exposed. Then, we do like to have our technicians, our artists, and what we’ve developed internally here to be recognized and shown to the public, just so that people can see how cool it all is.

I think, though, that my response to those kinds of news stories is really more of a happiness to see new technologies being developed elsewhere, and an eagerness to get my hands on it so I can see what we could do with it in a movie. And, of course, sometimes we develop our very own things here that maybe someone hadn’t thought of, and that could be of use in other fields, like robotics. And that’s kind of cool, too.

Manaugh: Finally, to bring things full circle, we’re just curious as to how Spectral Motion got started.

Elizalde: Well, I became involved in the effects industry back in 1987. It sort of just dawned on me one day that I wanted to do this for a living. I had been in the Navy for eight years when it really started getting to me—when I realized I wasn’t doing what I wanted to do with my life.

I decided that I’d come back to my home, which is Los Angeles, California, and look into becoming a creature effects guy. I was totally enamored of Frankenstein’s Monster when I was a kid. I grew up watching all the horror movies that I could see—a steady diet of Godzilla, Frankenstein, you name it. All the Universal monsters, and even more modern things like An American Werewolf in London. They just really fascinated me. That was a real catalyst for me to start exploring how to do this myself.

I also learned from books. I collected books and started using my friends as guinea pigs, creating very rudimentary makeup effects on them. And, eventually, I landed my first job in Hollywood.

Cut to fifteen years later, and I had my first experience on set with Guillermo del Toro. I was working with him on Blade II. I had done an animatronic device for the characters he was using in his film, and I was also on set puppeteering. We became very good friends. That’s when he offered me the script for Hellboy and that’s how we started Spectral Motion. I became independent. Prior to that I had worked for Rick Baker, and Stan Winston, and all the other big names in town. But this was our opportunity to make our own names—and here we are, today.

You know, this is one of those industries where you can come in with a desire and some ability, and people around you will instruct you and nurture you. That’s how it happened for me. I was taught by my peers. And it really is a great way to learn. There are schools where you can learn this stuff, as well, but my experience proved to me that the self-taught/mentored method is a very good way to go.


On a tip from Nick Blomstrand, one of the students from Unit 11 at the Bartlett School of Architecture, with whom Venue had the pleasure of traveling through Florida for a week while they did research for their various design projects, we stopped by the former hollow-earth cult settlement—and now state historic site—in the purpose-built town of Estero.



Estero was founded in 1894 by Dr. Cyrus Reed Teed, who, following a spiritual awakening, renamed himself Koresh. The National Park Service (PDF) describes Estero as "a 19th-century post-Christian communistic utopian community."

The meandering but precisely designed network of paths laid down to connect buildings on the coastal site were all paved with hundreds of thousands of seashells so that the walkways could reflect moonlight, a geometric garden illuminated by the sky.



One of the central beliefs of the Koreshan community was that human beings live on the convex inner surface of a vast hollow sphere, with the sun and stars all burning inside, at a central point around which the surface of the earth is wrapped.

To demonstrate the concept, Koresh produced several small models: globes within globes that he then took with him to various fairs and public lectures, seeking to find (or to convert) fellow planetary free-thinkers.

As it happens, hollow earth cults were not, in fact, entirely uncommon for the era—Jules Verne's classic science fiction novel Journey to the Center of the Earth, for example, exhibits tinges of hollow earth thinking and even Edgar Allan Poe's "Descent into the Maelstrom" was influenced by ideas of a hollow earth with hidden entrances, amidst great and dangerous landscapes, at the earth's poles.

Indeed, as David Standish writes in his book Hollow Earth: The Long and Curious History of Imagining Strange Lands, Fantastical Creatures, Advanced Civilizations, and Marvelous Machines Below the Earth's Surface, it was Sir Edmund Halley, of Halley's Comet, who "gave us our first scientific theory of the hollow earth—in his formulation, consisting of independently turning concentric spheres down there, one side the other. Halley arrived at this notion, which he presented to the prestigious Royal Society of London, to account for observed variations in the earth's magnetic poles. His true imaginative leap, however, lay in the additional thought that these interior spheres were lit with some sort of glowing luminosity, and they they might well be able to support life. Generations of science fiction writers"—not to mention "communistic" utopians—"have been thankful to him for this ever since."



However, the Koreshan community at Estero sought to make good on the spiritual-scientific promise of these theories by taking them one step further into the realm of empirical testing and experimentation. That is, they attempted to prove, by way of homemade geodetic instrumentation and other landscape survey tools, that the earth is hollow and that, as they describe it, "we live inside."

Enter the so-called Rectilineator, a massive measuring rod—or, as science writer Frank Swain joked recently at a talk in Amsterdam, "a really big ruler"—that could be easily assembled and disassembled in large modular sections. Thus advancing down the smooth sloping beaches of south Florida, the Rectilineator would gradually do one of two things: either 1) it would depart from the earth's surface, thus proving that the earth, alas, was the way everyone else said it was and that we lived on the outside of a concave sphere, or 2) it would move closer and closer to the earth's surface, thus proving, on the contrary, that the Koreshans were correct and that the earth's surface was convex, slowly curving up into the sky, thus proving that we live inside a hollow earth.

The Rectilineator in action.

It should not come as a surprise to learn that the Koreshan beach survey of 1897 "proved" that the earth was hollow, thus vindicating Dr. Cyrus Teed in the eyes of the people who had followed him to what was, at the time, a subtropical backwater in a thinly populated state.

Things went downhill, so to speak, from there. After an ill-advised step into local politics, and a disastrous miscommunication with the local police force, Dr. Cyrus Teed was beaten to death, his theorized resurrection never came, and the cult slowly disbanded, leaving their settlement behind, intact, a town full of pseudo-scientific surveying tools abandoned to the swamp.



In 1976, what remained of the site was cleaned up and added to the National Register of Historic Places, becoming the Koreshan Unity Settlement Historic District. You can now visit the site—located alarmingly close to a freeway—and walk the shell-paved paths, wandering from cottage to cottage past a number of small historic displays, trying to tune out the sounds of passing cars.



Briefly, the aforementioned science writer Frank Swain, while discussing the Koreshan Unity settlement and the Rectilineator they used to measure the curving earth, provocatively compared their survey tools to NASA's so-called LISA satellite mission, which is, in Swain's words, also "a really big ruler" in space.

The LISA mission, more specifically, will use three laser-connected satellites placed five million kilometers apart in deep space to measure gravitational waves and the warp & weft of spacetime itself—a kind of Rectilineator amidst the stars, proving or disproving whatever theories we care to throw at it.


While in Denver, Colorado, Venue had the pleasure of making a childhood fantasy come true: an all-day backstage pass to the city's public library, complete with a private introduction to room after room full of maps, books, paintings, photographs, architectural drawings, and other collections documenting the people, places, and events that shaped the settlement and growth of the western United States.

The Denver Public Library building, designed by Michael Graves & Associates.

From a meandering tour of the new Postmodern library building, designed by architect Michael Graves in the 1990s, to a covetous browse through the city's old fire-insurance maps produced by the Sanborn Map Company, via a quick mention of the Denver Police Intelligence Files and a thorough bibliography of reference materials related to Denver's saloon cats, it was an exhilarating day of flipping through card catalogs, stepping behind closed doors, following off-limits stairways up to archives not usually open to the public, and learning more not only about the history of Denver and the West, but also about library science, more generally, and about our guide for the day, Senior Special Collection Librarian Wendel Cox, more specifically.

Venue's vote for best card catalog entry ever—a Franz Feneon-worthy novel in two lines, filed under "Horses. Biography."—was brought to our attention by Wendel Cox.

There's no real way, however, without writing our own Ulysses of the Denver Public Library—describing every unexpected turn of conversation, every artifact, every cross-connected historical reference (rabies to quarantine to the library's medical collections) and every other thing seen, read, or pored over in nose-to-paper levels of detail during the day—to encapsulate all that took place during Wendel's enthusiastic introduction to the collections; so, instead, we'll just focus on a few particular highlights, cartographic in emphasis and origin.

Senior Special Collection Librarian Wendel Cox shows us a hand-drawn map of New Mexico and Utah.

First, the fire maps.



The Sanborn Map Company produced, between 1866 to 2007, some of the most extraordinary and historically useful maps of the urban United States available in any collection today.



Almost all major municipal libraries in the country maintain voluminous back-stocks of them, their heavy pages over time thickened past the point of bendability by endless glued layer after layer of property updates, infrastructural upgrades, new construction, and the entire re-routing of streets and whole neighborhoods at a time.



Peeling, partially unstuck, and warped into curling waves like oceans, the pages play host to a century or more of built structures, renovations, and replacements, keeping close tabs on what can be insured, for how much, and under what circumstances.



These Sanborn maps are as near-total a catalog of the city's development over time as can be cartographically imagined, with almost every square inch built up into thick scabs of structures upon structures, upon even more structures.

Every pasted edge conceals a preserved strata of earlier revisions and additions, all but daring us to pick at it (we resisted), tempting us to pull ever so slightly at the looser corners, to lift up the surface layer and reveal the other city—there is the city and then there is the city, as novelist China Miéville might describe it, the two, surreally, existing in the same place at the same time—that lies beneath today's Denver, with its competing but complimentary property lines, a city out of synch with itself as you peel away the layers of history.



Each page, as Wendel showed us, turning carefully through the old volumes, is like a plank of wood at this point, archaeologies of layers laminated into something almost more like furniture.

These are books as Kafka might imagine them: enormous, absurd, and so preposterously heavy with the details of local history as to be physically unmanageable. They are books that could wound the librarians who handle them, slipping discs and offsetting spines, causing even historians to second-guess turning their pages.



But this (exaggerated) sense of physical threat is, of course, echoed in the book's content: as we navigated Denver's neighborhoods, we developed a sense for the city as a place of fire risks and dangerous proximities, a city of escape-assisting back alleys counter-balanced by wood-framed meeting halls, its spaces rated for their performance during events of conflagration.

And, in the process, we saw the city as a series of surfaces built up over time, fractally expanding across the Front Range.



The second thing—of many things—worth mentioning was a decidedly less antique item from the collection: a map and pamphlet, produced by the U.S. Geological Survey and compiled by Glenn R. Scott between 1972 and 2004, called Historic Trail Maps in Eastern Colorado and Northeastern New Mexico (you can download the accompanying 45mb PDF here).



As the map's introduction, written by former USGS Director Charles G. Groat—who recently resigned from the University of Texas in a controversy over financial ties to the fracking industry—explains, many of the "historic trails that were the primary pathways used by pioneers to open the Western United States" have been forgotten or erased entirely.

These trails, he continues, "have names that remain familiar today—Santa Fe, Overland, Cherokee, Trappers, Republican Fork, and Smoky Hill Trails. Some of those historic trails have long-since vanished or are now only faintly visible on today’s landscape."

Scott's map and pamphlet are thus an act of preservation, the USGS explains, saving for future generations the wide range of "historic marks left on the land by Native Americans, trappers, prospectors, early road builders, and settlers from about the 1820s to about 1900."

Put another way, Scott made a map of lost roads.

A long slice of the Glenn R. Scott's USGS map, showing lost roads, trails, and camps to the south and east of Denver, Colorado.

As Groat writes in his introduction to Scott's work, the routes and place-names gathered on the map tell the human history and usage of the Coloradan landscape:

Features of the maps include trails used by Native American tribes and trappers before the arrival of European settlers. As the westward movement continued, trading posts, immigrant and prospector trails, stagecoach lines and stage stations, wagon roads, and railroads marked that expansion, and those features are shown on the maps. From the cattle trails and trails over mountain passes to the towns and military camps and forts, the settlement and use of these lands are captured for posterity. Routes taken by prospectors during the great 1859 Gold Rush to the Pikes Peak gold fields are portrayed, as are the world-famous mining camps that followed, including Central City, Blackhawk, Idaho Springs, Georgetown, Fairplay, Aspen, Breckenridge, Leadville, and Cripple Creek. In addition, the routes traversed by early explorers such as Zebulon M. Pike, Stephen H. Long, and John C. Fremont are shown on the maps. The maps reflect the Hispanic and French heritage of much of the region, and the rich history of New Spain, Mexico, and France are imprinted in the names of numerous mountain ranges, prominent peaks, valleys, rivers, and towns.

Scott's own story, meanwhile, is fascinating—equal parts folklore and geological survey of the American West:

Beginning in 1964, Scott realized that in addition to relating the geologic record there was an entirely different story he also wanted to tell. He was fascinated by the historic trails he encountered during his geology fieldwork—trails used by Native Americans and by pioneers and prospectors who settled in Colorado and New Mexico. He resolved to document those trails before they forever vanished. Using aerial photographs, long forgotten historical archives, and other historical texts, he located historic trails all over eastern Colorado and northern New Mexico, and in 1972 he published the first of his 11 historic trail maps.




Indeed, in a nicely circular reference, Scott himself writes that "most of the information I used came from the Denver Public Library, where I was a volunteer in the Genealogy and Western History Department." At the risk of over-using the analogy, he was a kind of James Joyce of the eastern Rockies, going back through deeds of sale, acts of incorporation for now defunct road-building companies, and, no doubt, Sanborn maps, in search of old ways across the landscape.

In a much longer pamphlet listing the sources used for his map, Scott gives some examples of the sorts of narrative coordinates that are all that remains of certain trails:

Starting at Bergen's house and down the gulch southeastward by the Hendershott's house to Myer's Mill on Bear Creek thence by the most practicable route by Luther's place and Parmalee's sawmill to the Turkey Creek Road at the mouth of the gulch opposite Parmalee's water mill on Turkey Creek.

Or:

From Boulder City, Boulder County, up and along north side of North Boulder Creek as far as practicable and best route to Central City, Gilpin County.

To which he occasionally adds his own surreal story-form updates, as if the information presented is now that much clearer:

Route was changed as follows: from American Avenue on the west bound- ary of Empire City extending 3 miles up the south bank of Clear Creek, then crossing and extending 3/4 mile up the north bank, recrossing and then 700 feet up the south bank, recrossing and then continuing up the north bank on the route designated in the original article, then up to and thru Vasquez Pass, then on the original route to Bangs or Corral Creek, the western terminus in the original article, then outside the area.

Perhaps most evocative of all, there are also entries that simply read:

Route unknown.



These are the "old ways," as author Robert Macfarlane describes the similarly forgotten trails and routes that spider the landscape of the United Kingdom. In his book of that name, Macfarlane writes that, "once you begin to notice them, you see that the landscape is still webbed with paths and footways—shadowing the modern-day road network, or meeting it at a slant or perpendicular. Pilgrim paths, green roads, drove roads, corpse roads, trods, leys, dykes, drongs, warns, snickets—say the names of paths out loud and at speed and they become a poem or rite—holloways, bostles, shutes, driftways, lichways, ridings, halterpaths, cartways, carneys, causeways, herepaths."

The incantatory geography that Macfarlane refers to is in Britain, but, as Glenn R. Scott's map shows, the prairies, hills, and mountains of the American southwest have their own slowly eroding memory bank of old ways seamed into the ground by human feet, horses, and post wagons.



Briefly, Scott's labyrinthine explorations of trail folklore and historical cartography in Colorado also brings to mind a story published nearly five years ago in The New York Times, on an effort by Vermont's towns and cities to catalog their "ancient roads."

As the Times explained, a 2006 state law had given Vermont residents a strong incentive to rediscover their state's buried and forgotten throughways by allowing municipalities to claim them as official town lands (thus ensuring that they remain as public lands, unable to be claimed by private landowners). As a result, the Times reported, "citizen volunteers are poring over record books with a common, increasingly urgent purpose: finding evidence of every road ever legally created in their towns, including many that are now impassable and all but unobservable."

These "elusive roads"—many of them "now all but unrecognizable as byways"—are lost routes, connecting equally erased destinations. In almost all particular cases, they have barely even left a trace on the ground; their presence is almost entirely textual. They are not just lost roads, in other words, mere unstable geographies flashing in and out of county land registers. They are road that have been deterrestrialized: scrubbed from the surface of the earth.

As the Times acknowledges, "Even for history buffs, the challenge is steep: evidence of ancient roads may be scattered through antique record books, incomplete or hard to make sense of." Accordingly:

Some towns, content to abandon the overgrown roads that crisscross their valleys and hills, are forgoing the project. But many more have recruited teams to comb through old documents, make lists of whatever roads they find evidence of, plot them on maps and set out to locate them.

Like something out of the geography-obsessed poetry of Paul Metcalf—part map, part deep social history, part regional etymology for re-reading place names as the myths that they are—the descriptions found in these old municipal documents are narrative, impressionistic, and vague, perfectly in tune with what Glenn R. Scott found in Colorado.

Returning to The New York Times, for instance, these descriptions "might be, 'Starting at Abel Turner’s front door and going to so-and-so’s sawmill,' said Aaron Worthley, a member of the ancient roads committee in Huntington, southeast of Burlington. 'But the house might have burned down 100 years ago. And even if not, is the front door still where it was in 1815? These are the kinds of questions we’re dealing with.'"

As Wendel told us, these sorts of cryptic references to lost byways are not only of interest to local historians—attorneys form another interest group who consult the Denver Public Library's archives with some frequency. In Vermont, too, the Times reports that these acts of perambulatory interpretation came to be part of a much larger, although fairly mundane, attempt to end "fights between towns and landowners whose property abuts or even intersects ancient roads."

In the most infamous legal battle, the town of Chittenden blocked a couple from adding on to their house, saying the addition would encroach on an ancient road laid out in 1793. Town officials forced a showdown when they arrived on the property with chain saws one day in 2004, intending to cut down trees and bushes on the road until the police intervened.

The article here goes on to refer to one local, a lawyer, who explains that "he loved getting out and looking for hints of ancient roads: parallel stone walls or rows of old-growth trees about 50 feet apart. Old culverts are clues, too, as are cellar holes that suggest people lived there; if so, a road probably passed nearby." Think of it as landscape hermeneutics: peeling back the layers in the map to reveal a vanished landscape.


"Botanical Profile representing the Forest Trees along the route explored by Lieut. A. W. Whipple, Corps. of Top. Eng., near the Parallel of 35º North Latitude, 1853-1854." Prepared by J. M. Bigelow, M.D., Botanist to the Expedition. U.S. Pacific Rail Road Exploration & Survey, War Department.

Wendel led us on through the archive's sedimentary record of human movement across the Coloradan landscape, from a filing cabinet stuffed full of railroad timetables and accident records to an overflowing folder of newspaper clippings on Denver International Airport conspiracy theories. A mournful subsection focused on anticipatory documentation of future erasures: a gorgeous 1854 botanical profile of a proposed U.S. Pacific railway route and the business-like binders of the much more recent I-25 environmental impact assessment.



Our day in the Denver Public Library was itself a kind of lost trail, as we noted with amusement that various quirks of the building made it hard to remember which stairwell we had taken to get to a certain floor—and, thus, whether we could even access that floor or the collections Wendel Cox had in mind for us—and it became abundantly clear that even libraries have their own kind of curatorial folklore, a personal but by no means written down knowledge of where to find certain books, objects, files, or collections, what those artifacts, in turn, mean for other things encountered in the archive, and how certain narrative strands tie a library, and a landscape, together from within.

Many thanks to Myra Rich for suggesting that Venue should meet with Wendel Cox, and for making the introduction, as well as to Wendel himself, for sharing his time and knowledge so generously. This post contains a few paragraphs previously published on BLDGBLOG.
Perky's Bat Tower stands at the end of an unmarked dirt road on Sugarloaf Key as a striking, albeit unsuccessful, monument to both biological pest control and cross-species design.


Before the Florida Keys meant sun, sea, and Jimmy Buffet, they were famous for mosquitoes—dense, black clouds of them that hummed and bit without pause, spread malaria, dengue, and yellow fever, and drove visitors temporarily insane with irritation.

In the late nineteenth century, the Broward Palm Beach New Times reported swarms "so dense in some areas that it was impossible to breathe without inhaling mouthfuls of mosquitoes." A twentieth-century entomologist caught a terrifying—and record-breaking —"365,696 mosquitoes in one trap in one night" on an island just off the tip of the Florida peninsula, according to Michael Grunwald's book, The Swamp.

And, in the 1920s, hordes of mosquitoes were the major obstacle standing between Richter Clyde Perky, a real estate developer from Denver, and the success of his fishing resort on Lower Sugarloaf Key. The construction manager Perky had hired to oversee the project complained that "in the late afternoon, you would just have to rake the bugs off your arm" and that "they'd form a black print on your hand if you put it against a screen and suck all the blood right out of it."



In his search for a solution, Perky came across a book called Bats, Mosquitoes, and Dollars by Dr. Charles Campbell. A doctor and "city bacteriologist" based in San Antonio, Texas, Campbell had been experimenting with attracting bats to artificial roosts since the turn of the century, in the belief that they were the natural predators of mosquitoes. As an article in BATS magazine explains, Campbell initially thought that the design of bat architecture would be a simple matter:

"Can bats like bees be colonized and made to multiply where we want them?" he wondered. "This would be no feat at all!...Don't they just live in any old ramshackle building? They would be only too glad to have a little home such as we provide for our song birds..."

After a handful of expensive failures, followed by several months spent in the caves of West Texas, observing bats in their natural environment, Campbell came up with his pioneering design for a Malaria-Eradicating Guano Producing Bat Roost, "built according to plans furnished by the greatest and only infallible of all architects, Nature," and equipped with "all the conveniences any little bat heart could possibly desire."

His new tower, claimed as the world's first successful intentional artificial bat roost, was built next to Mitchell's Lake, ten miles south of San Antonio, in spring 1911. Malaria cases in the neighborhood decreased, Campbell cleared hundreds of dollars in guano sales, and the Mitchell's Lake tower was soon followed by more than a dozen more built to the same design, one as far afield as Italy.



Perky obtained the roost plans from Campbell in 1929, and constructed his own tower at a cost of $10,000. More than thirty feet tall, and sturdy enough to have weathered dozens of hurricanes over the past eighty years, the tower still features a louvered bat entrance facing the prevailing wind, a central guano removal chute, and a dense, honeycombed walls of cypress wood bat corrugation that function as roosting shelves.




Sadly, despite a lavish application of pheromone-doused guano as bait, not a single bat ever moved into in the palatial accommodations Perky had provided. (In fact, the first scientifically confirmed colony of bats in the Keys was only found in 1996.)

Today, the Florida Keys Mosquito Control District regards Perky's Bat Tower as their founding monument, but relies instead on a full-time team of seventy-one employees armed with handheld foggers, spray trucks, four helicopters, and two fixed-wing aircraft from which to dispense regular doses of larvicide granules and pesticide sprays onto the landscape. They are currently contemplating a not uncontroversial return to biological control with the purchase and release of genetically-modified mosquitoes, whose offspring die upon hatching.



Meanwhile, Perky's tower is finally home to a winged animal. Standing in a pool of stagnant, mosquito-friendly water, the weathered pine pyramid is currently topped with an active osprey nest—architecture by animals atop architecture for animals.
