Across 524 square miles, under one square mile of Mecklenburg County maps onto soluble rock. With about 1,206,285 residents (2,304 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 546 map points about 1.0 miles apart, so a pocket smaller than that can be missed or overstated.
