Across 566 square miles, under one square mile of Brunswick County maps onto soluble rock. With about 15,750 residents (28 per square mile), much of the land is open, and the mapped rock may sit far from where people actually live. The figures come from 320 map points about 1.3 miles apart, so a pocket smaller than that can be missed or overstated.
