Across 799 square miles, under one square mile of Erie County maps onto soluble rock. With about 267,750 residents (335 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 243 map points about 1.8 miles apart, so a pocket smaller than that can be missed or overstated.
