Across 902 square miles, under one square mile of Kanawha County maps onto soluble rock. With about 173,906 residents (193 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 515 map points about 1.3 miles apart, so a pocket smaller than that can be missed or overstated.
