Get Lost in a Corn Maze That Looks Like a Microscopic 'Water Bear'

When Angie Treinen first learned about
tardigrades a few years ago, at a family-friendly science event at the
University of Wisconsin, she couldn’t believe it. She loved their
squashed little faces and their wonderfully rotund bodies, which look
like a puffy stack of partly melted marshmallows. “I just stood there
the whole time like, ‘Are you kidding me?’” Treinen says.
Treinen studied zoology
and worked as a veterinarian, but had never encountered teeny tiny
tardigrades, which are variously known as moss piglets and water bears.
Immediately, they captivated her. Typically less than a millimeter long,
tardigrades thrive in both mundane and extreme conditions, including
bone-rattling icy landscapes, oceans, and ultra-hot environments.
(They’re probably flourishing near your house, too, and it’s easy to meet them.)
Internet audiences love them because they’re endearingly goofy, like
claymation creatures loping around on impossibly spiky claws.
Researchers, meanwhile, are fascinated by their ability to stay alive: Tardigrades persist in the face of pressure changes, temperature fluctuations, and vanishing water and oxygen.
So when Treinen sat
down to plan out the annual corn maze for the eponymous farm she owns
with her husband in Lodi, Wisconsin, it seemed obvious. 2020, a year of
disease, economic recession, and crushing ennui, would be the year of
the tardigrade. Treinen talked to Atlas Obscura about designing, planting, sculpting, and welcoming visitors to the 15-acre corn maze, which is open at Treinen Farm through November 8, 2020.
What makes for a good maize maze?
We have a lot of parameters. It typically
needs to be a story, or something really intriguing—we’ve done Aesop’s
fables and some Greek myths, like Icarus. It has to be a recognizable
figure: When the picture of the maze is online, I don’t want people to
be confused, like “What is that?” But I try to do a completely different
art style each year. We did a Picasso-sketch style one year, and Art
Nouveau another. Sometimes it looks like stained glass; sometimes it
looks like folk art. I don’t want my mazes to all look exactly the same.
I’m also aware of what is challenging for visitors to navigate in the
maze. I want people to get lost, and I want there to be a lot of
challenge—but not so much that people are like, “I’m outta here and I’m
never coming back.”
How do you design them?
I fill up my Pinterest page with
interesting things, and then I start sketching by hand—just rough, rough
sketches so that I have an idea what the main figure and layout might
be. Then I do almost all of it in Illustrator. My ultimate product is a
black-and-white line drawing.
How does maze design affect the planting?
My husband plants the field
in vertical and horizontal rows, which is not how you normally grow
corn. But he does this so there’s literally a grid growing right into
the field, with each row about 30 inches from the next, so it becomes a
dense field. When I am done with the design, I put a grid on a layer in
the Illustrator, which matches the grid he’s planted in the field.
The design typically takes me about 10
days. I start in June, on the day that the corn goes in. Ten days is the
time between when you plant the corn and the time it’s going to be up
in visible rows—and if the weather’s warm, it comes up even faster. You
have to cut the corn while you can still see what the rows are. Once it
gets to be about knee-high, the leaves of the corn are starting to
overreach, and you can’t distinguish the rows anymore. So that’s the
deadline. One year it came up in six days, and my husband was like, “The
corn is up. I need the design.” I need that pressure.
How do crews go in and make the maze?
I print the plans out and
give them to the maze-cutting crew. They’re able to find a point on my
plan and then, by counting rows, they put stakes and flags out and find
the corresponding parts in the field. They paint where the trails need
to be, and they mow them first before tilling the fields [and ripping up
the roots]. We have a commercial mower about five feet wide. If there’s
a mistake when you mow the corn, it’ll grow right back (and I can
usually alter the map to match the mistake). It takes about 120 to 150
person hours to cut the maze. Periodically, I take my drone up to verify
things are looking ok.
The maze crew loves it when there’s a lot
of circles or parts of circles, because circles are easy to cut. I can
mark on the design the center of the circle and the radius. Somebody
stands at the center, takes a measuring tape, pulls it out to the
radius, and then just walks around in a circle. Anything geometric is
also easy for them to cut, because of the clear angles. Art Deco
borders, or specific flourishes which need to be precise, they get a
little complain-y about those things. But they always do it just fine.
This year, the maze is more organic. All of those paths are not set in
stone.
What’s the experience like for a visitor? Will they have any sense that they’re exploring a tardigrade?
The corn is about 10 feet tall now. The
only way you can see the tardigrade is to be up in the air. We have a
tower that you can walk up and overlook the maze, but you can’t really
see the design—just some of the swirls. You have to be up in an airplane
or use a drone to really see it. What the visitors are seeing is
corridors of corn that all look the same, basically.
You’ve done other science mazes in the past, such a trilobite, Wisconsin’s state fossil, in 2017. What appealed to you this year about tardigrades?
This year, when I was designing the maze,
I was anxious, as everybody else probably was, too. I didn’t know what
the future was going to be. I didn’t even know for sure if we were going
to be able to open our business at all. But my husband said, “You know
what, we’re going to put all the pumpkins in, we’re going to put the
maze in. We can’t do it if we don’t have those things.” I was thinking
how resilient water bears are. I mean, come on. That has to be the 2020
corn maze. A lot of people said to me, “Oh, why don’t you do a virus?”
I’d like to be a place where people don’t have to think about it for two
hours. But I did want to acknowledge that it’s really hard right now.
How does a maze made of living corn change over the course of its run?
Right now, the corn is as tall as it’s
going to be. But even after it stops growing vertically, it grows these
tassels, which hold pollen. Then the pollen falls where the ears are
going to be, and then the ears grow. The most important thing is that
the corn stalks be really strong and that the leaves stay green for as
long as possible, because when they dry, they get brittle and kind of
break, and then your maze looks really sparse. Ours will get killed by
the frost around the beginning of October. By the end of the season,
it’s brown. Eventually, we harvest it and sell it [typically for animal
feed].
This year’s maze recently opened to the public. How have visitors reacted so far?
One of the first people
who came in had a tardigrade tattoo. That is honestly one of the most
amazing things I’ve seen in a really long time. The visitors we’ve had
so far really want to talk about tardigrades; they’ve gone to our
website and clicked on all the links and learned about them. Somebody
said they had found tardigrades and had a microscope and were taking
care of them. I thought, “Wow, okay, I think I probably need to do
that.”
