What the Civilian Conservation Corps Left Behind on Ozark Glades

Eighty years ago this month, the National Park Service handed over Lake of the Ozarks State Park to Missouri’s care. The CCC boys who built it in the 1930s were long gone by then, but what they left behind still stands — log buildings fitted without nails, stone dams that hold water to this day, rustic bridges that have carried three generations of families across Ozark hollows. I think about those young men sometimes, building structures meant to outlast them by centuries, and I wonder if they knew.

This week I’ve been watching the dolomite glades come alive, which feels like the right time to think about things that endure. If you’ve never seen a glade in late April, it’s something. These ancient exposed plateaus — 230 million years old, give or take — host plants that have learned to thrive where most things give up. Prairie larkspur is blooming now, those pale blue-green spires that look almost too delicate for the rocky soil they call home. And if you look carefully, you might spot Missouri foxtail cactus, a native that most folks don’t even realize grows this far north.

What makes glades remarkable isn’t just what grows there. It’s what the growing teaches you about adaptation. Dolomite rock creates alkaline soil that would stress most garden plants into oblivion. But larkspur and cactus figured it out, the way the CCC boys figured out how to build with native stone and timber in terrain that didn’t make anything easy.

A Lesson in Soil and Plants

For families looking to get outside this week, here’s something worth trying. Bring a simple soil pH test strip — you can pick them up at any garden center — and let your kids test the soil on a glade versus a shaded forest floor nearby. The difference will surprise them. Glade soil runs alkaline because of that ancient dolomite bedite, while forest soil trends acidic from all those decomposing leaves. Then have them sketch the plants they find in each spot and ask the question: why do different plants choose different ground?

If you’re in the southwestern Ozarks near the White River Hills, keep your eyes open for elk sign too. We’re in the window before May calving, and the herds are moving with purpose through open glades. Fresh tracks, tree rubs, flattened grass where they’ve bedded down — it’s like reading a newspaper written in the land itself.

I’ve been thinking lately about what we leave behind. Those CCC workers built for people they’d never meet. The plants on these glades have been adapting for longer than humans have walked this continent. And somewhere in between, we get to decide what we’re tending and what we’re passing on.

Explore the Glades This Week

If you’d like to see glade ecology up close, our trails at the preserve cross several exposed dolomite areas that are blooming right now. Bring your soil test strips. Bring your sketchbook. Bring the questions your kids ask that you don’t know how to answer, because those are usually the best ones.

Or try it in your own backyard this week. Find the spot where grass won’t grow no matter what you do, and instead of fighting it, ask what it might be trying to tell you. Sometimes the ground knows something we haven’t learned yet.
