Across 632 square miles, under one square mile of Washington County maps onto soluble rock. With about 58,332 residents (92 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 517 map points about 1.1 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 these percentages are measured.
