Across 980 square miles, under one square mile of McKean County maps onto soluble rock. With about 39,478 residents (40 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 372 map points about 1.6 miles apart, so a pocket smaller than that can be missed or overstated.
