Across 880 square miles, under one square mile of Caddo Parish maps onto soluble rock. With about 224,893 residents (256 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 1.3 miles apart, so a pocket smaller than that can be missed or overstated.
