What to do about a house in Jasper County

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

That works out to roughly 352 of Jasper County's 560 square miles on soluble rock. With about 33,387 residents (60 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 334 map points about 1.3 miles apart, so a pocket smaller than that can be missed or overstated.

Worth reading for this county: why the 63% under cover still counts, and how these percentages are measured.
