Across 329 square miles, under one square mile of Washington County maps onto soluble rock. With about 130,333 residents (396 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 439 map points about 0.9 miles apart, so a pocket smaller than that can be missed or overstated.
