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.”
