Across 758 square miles, under one square mile of Poinsett County maps onto soluble rock. With about 22,300 residents (29 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 396 map points about 1.4 miles apart, so a pocket smaller than that can be missed or overstated.
