Across 497 square miles, under one square mile of Lamar County maps onto soluble rock. With about 66,734 residents (134 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 347 map points about 1.2 miles apart, so a pocket smaller than that can be missed or overstated.
