Across 735 square miles, under one square mile of Pratt County maps onto soluble rock. With about 9,137 residents (12 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 400 map points about 1.4 miles apart, so a pocket smaller than that can be missed or overstated.
