Across 571 square miles, under one square mile of Logan County maps onto soluble rock. With about 694 residents (1 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 391 map points about 1.2 miles apart, so a pocket smaller than that can be missed or overstated.
