Across 946 square miles, under one square mile of Nacogdoches County maps onto soluble rock. With about 65,728 residents (69 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 596 map points about 1.3 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.
