Has Iowa always had Wetlands?
If you didn't know, Iowa was once passed over by a glacial drift. That's right, the Ice Age happened right on top of Iowa. So what does that have to do with wetlands? Let us explain: these glaciers that once surfaced over our land began to melt, and when they did, they started sliding just like a giant ice cube. The glaciers weighed millions of tons, so when they began to slide and wiggle, they carved the earth beneath them. We call this "glaciation", and it produced potholes in the ground along with lose rock or sand, and Hardin County's scenic bluffs. The melting water filled the craters and turned them into ponds, creating a unique historical landscape like here in Hardin County. This landscape is commonly referred to as the prairie pothole region. Alongside these prairie potholes and rock outcrops are a mix of native grasses, forbes, and shrubs which took root and created Iowa's diverse wetlands ecosytems.
