Across 453 square miles, under one square mile of Logan County maps onto soluble rock. With about 30,560 residents (67 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 546 map points about 0.9 miles apart, so a pocket smaller than that can be missed or overstated.

Two things to read before deciding: how these percentages are measured, and the warning signs that apply anywhere.
