Across 645 square miles, under one square mile of Wood County maps onto soluble rock. With about 48,742 residents (76 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 291 map points about 1.5 miles apart, so a pocket smaller than that can be missed or overstated.

Two things to read before deciding: why gypsum and salt move faster than limestone, and how ground with no limestone still opens up.
