Across 604 square miles, under one square mile of Washington County maps onto soluble rock. With about 37,810 residents (63 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 249 map points about 1.6 miles apart, so a pocket smaller than that can be missed or overstated.
