Across 252 square miles, under one square mile of Aransas County maps onto soluble rock. With about 25,595 residents (101 per square mile), homes are spread across towns and farmland, and a mapped unit may or may not reach the developed parts. The figures come from 496 map points about 0.7 miles apart, so a pocket smaller than that can be missed or overstated.
