Across 784 square miles, under one square mile of Walker County maps onto soluble rock. With about 83,722 residents (107 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 268 map points about 1.7 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.
