Across 426 square miles, under one square mile of Ashe County maps onto soluble rock. With about 27,266 residents (64 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 267 map points about 1.3 miles apart, so a pocket smaller than that can be missed or overstated.
