Across 225 square miles, under one square mile of Forsyth County maps onto soluble rock. With about 280,096 residents (1,247 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 262 map points about 0.9 miles apart, so a pocket smaller than that can be missed or overstated.
