Across 1,042 square miles, under one square mile of Montgomery County maps onto soluble rock. With about 749,613 residents (719 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 604 map points about 1.3 miles apart, so a pocket smaller than that can be missed or overstated.
