What to do about a house in Lander County

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

That works out to roughly 419 of Lander County's 5,519 square miles on soluble rock, 419 of them with the rock at or near the surface. With about 5,785 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 263 map points about 4.6 miles apart, so a pocket smaller than that can be missed or overstated.
