Across 5,959 square miles, under one square mile of Fresno County maps onto soluble rock. With about 1,024,125 residents (172 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 372 map points about 4.0 miles apart, so a pocket smaller than that can be missed or overstated.
