Across 753 square miles, under one square mile of Shelby County maps onto soluble rock. With about 910,530 residents (1,210 per square mile), most of the county is built up, so a mapped unit is likely to sit under somebody's street. The figures come from 286 map points about 1.6 miles apart, so a pocket smaller than that can be missed or overstated.
