What to do about a house in Presidio County

Sinkholes are uncommon here; watch for new depressions after heavy rain or leaking pipes.

That works out to roughly 116 of Presidio County's 3,855 square miles on soluble rock, 116 of them with the rock at or near the surface. With about 5,686 residents (1 per square mile), much of the land is open, and the mapped rock may sit far from where people actually live. The figures come from 595 map points about 2.5 miles apart, so a pocket smaller than that can be missed or overstated.
