Across 807 square miles, under one square mile of Minnehaha County maps onto soluble rock. With about 208,639 residents (259 per square mile), homes are spread across towns and farmland, and a mapped unit may or may not reach the developed parts. The figures come from 392 map points about 1.4 miles apart, so a pocket smaller than that can be missed or overstated.
