Across 581 square miles, under one square mile of Chester County maps onto soluble rock. With about 32,323 residents (56 per square mile), much of the land is open, and the mapped rock may sit far from where people actually live. The figures come from 341 map points about 1.3 miles apart, so a pocket smaller than that can be missed or overstated.
