The sky to the west was robin’s egg blue, a clearing in the day’s dose of clouds. They had just sneezed a handful of snow, already melting. I drove with the radio off. I didn’t know whether to wear my regular hiking boots or a pair of Wellington boots I’d packed at the last moment. The trail could be soggy, or maybe not. I was on my way to Sun Lake in Lake Villa, part of the Lake County Forest Preserves in northern Illinois.
For this month, I decided to revisit the idea behind my February 2019 post, when I explored a new-to-me preserve and wrote up my observations as a virtual tour. Readers seemed to enjoy it, and I enjoyed circling another name on the map I keep at my desk. So, here I was, about a year later, ready to chronicle another tour. Find a comfy chair and a warm mug. Here’s a snapshot of Sun Lake as I saw it.
Late last summer, I literally watched a groundhog (Marmota monax) fatten up before my eyes. He’d made a burrow in the field outside my office window and frequently visited the rain gardens around the Edward L. Ryerson Welcome Center in Riverwoods, part of the Lake County Forest Preserves in northern Illinois. We watched him scamper back and forth, snipping flower tops here and there, always with a mouth crammed full of flora.
Fast forward to early February, and as I look out across the same field, now dotted with small snow drifts punctuated by tufts of grasses gone tawny, I think about that groundhog curled tight in his burrow and deep in hibernation, oblivious to the hubbub of a day in his honor.

Yes, it’s almost that time of year. American mink (Neovison vison) mating season. I know, I’ve been waiting for it, too. February is celebrated for human romance: fancy dinner dates, shiny gifts, and long walks on the Des Plaines River Trail. But it’s useful to step out of our human-focused perspective once in a while. And thanks to our comprehensive Wildlife Monitoring Program, we know minks live in the Lake County Forest Preserves in northern Illinois. So, let’s examine why humans aren’t the only species that looks forward to February 14.
I keep thinking about angles. Not the kind you measure with a protractor, but those you measure with your mind. The angle of a story, a conversation, or a project. Photography, of course, uses physical angles—where’s the camera pointed? is the sun directly overhead or is it the sweet time of golden hour?—but the best photos make you want to see even more. They make you want to break open the frame and soak in every bit of the Lake County Forest Preserves in northern Illinois.
Since it’s nearly the end of 2019, I thought I’d turn 180 degrees and peruse the photos uploaded to our group Flickr pool since January 1. Suffice to say: we’re spoiled. Spoiled with the beauty of Lake County’s flora, fauna, and natural areas, and the talent of the photographers who capture it for everyone to see. Trees and shrubs in their bright fall wardrobes on either side of a trail draining into a vanishing point. A sandhill crane (Grus canadensis) with both wings up like a paper airplane as it dashes to take off. A whirlpool of stars spun around a rich blue sky over a tranquil wetland.
I’ve gathered these moments plus seven more below, but that’s only a small taste. I encourage you to browse the rest of the visual buffet as we make the turn out of the 2010s into the 2020s. And, hey! You might become inclined to upload that shot living on your phone, camera, or computer.
Come late November, most of us have turkeys on the brain. But a different type of turkey is taking to the skies at this time of year on its annual migration south: the turkey vulture (Cathartes aura). You can spot them in the sky or on the ground in the Lake County Forest Preserves in northern Illinois.
Everyone has one! At least, anyone who regularly hikes in the Lake County Forest Preserves in northern Illinois has one: a favorite trail. It might be the trail near your home or the one that reminds you of a secret only-I-know-about-this spot growing up. Maybe it holds a special memory. Whatever the reason, something about it always sparks joy in your heart.
Fall is the time of harvest here in the Midwest. Golden stacks of hay bales, farmer’s markets teeming with end-of-season produce, and above all, apples. But step away from the orchard and into an oak woodland and you’ll find a different kind of autumn apple: an oak apple gall. What looks like a small, lime-green, spotted apple dangling from an oak leaf is not a fruit at all, but rather a secret abode for a tiny wasp.
There are more than 50 species of oak apple gall wasps in North America. Each one creates a unique fruit-like structure that protects and feeds its eggs and larvae as they develop. Lately, I’ve been finding many dried, spent brown husks created by the larger empty oak apple wasp (Amphibolips quercusinanis) around the Lake County Forest Preserves in northern Illinois.
The dog days of summer are a bounty for the senses. We see the lemon-yellow of whorled sunflower blooms, taste the ripe flavor of a homegrown tomato, smell the spicy sweetness of bee balm flowers, feel the heat of the day and the cool of the evening. Yet the most quintessential sensation of these end-of-summer days is hearing the overwhelming cacophony of cicada songs around the Lake County Forest Preserves in northern Illinois.
The air was warm, the sunshine spread everywhere. Spiderwort blooms were freshly open, a waist-high meadow of bluish-purple fireworks. We found the steel T-post marking the start of the day’s first transect and the red flag for the first plot.
Then we gathered our tools. A one-meter-square collapsible wooden quadrat, retractable tape measure, clipboard, data sheets, and each other’s knowledge of plants.
Well, my own knowledge, not so much. I was there to take photos and observe the three experts onsite: Pati Vitt, Manager of Ecological Restoration; Ken Klick, Restoration Ecologist II; and Pete Jackson, who authored a 2009 study on this preserve’s plant communities that served as his thesis for a master’s degree program. In my head, I called them the Plant Team.
In my early twenties, I believed adventure was found in the tallest mountain, the deepest ocean, the largest cavern. I chased whales, orca, brown bears, bald eagles, and other charismatic megafauna. It took decades to realize I didn’t need to seek these animals or climb these mountains to find adventure. Some of the best adventure awaited me in my own backyard. This led me to join the Education Department at the Lake County Forest Preserves in northern Illinois in October 2018. What an adventure it’s been!
Anyone who’s attended a program taught by our staff or volunteers knows these educators are knowledgeable and passionate. This group ignited my latest adventure—birding—though I can’t point to a single component that sparked my newest hobby. It could have been my awe for the birders in this group, their love for birds and their impressive ability to bird by ear. It might have been my draw to a new challenge. The patience, attention to detail, and dedication it takes to be an effective birder. It may have been the rush of excitement, getting a glimpse of a rare species for a brief moment as it makes its annual migration. Perhaps all of these were feathery factors. Regardless, I’m hooked.
