The next step for one property

Check the parcel against your state survey sinkhole map, and ask for an inspection if cracks, depressions or sticking doors show up.

That works out to roughly 1,246 of Schleicher County's 1,311 square miles on soluble rock, 1,246 of them with the rock at or near the surface. With about 2,302 residents (2 per square mile), there is effectively nowhere in the county off the soluble rock, town or country. The figures come from 390 map points about 1.8 miles apart, so a pocket smaller than that can be missed or overstated.
