About the Refuge
This area also known as the Karst region, boasts topography of steep slopes and cliffs carved by the boundary of the ancient glacial stampede. Here the glacial deposits found in most of the surrounding area are not present.
The refuge encompasses 911 acres of the Driftless Area in Iowa, a small portion of the entire Driftless Area. This elevated craggy landscape found in 24,000 square miles of Iowa, Illinois, Minnesota and Wisconsin, escaped the slowly gliding ice of the Glacial Period or the Paleozoic-age, 500,000 years ago. The refuge also supports a rare community of plants and animals that take residence in the slopes.
