Across 268 square miles, under one square mile of DeKalb County maps onto soluble rock. With about 770,307 residents (2,878 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 245 map points about 1.0 miles apart, so a pocket smaller than that can be missed or overstated.
