What to do about a house in Curry County
No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.
That works out to roughly 3 of Curry County's 1,628 square miles on soluble rock, 3 of them with the rock at or near the surface. With about 22,774 residents (14 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 593 map points about 1.7 miles apart, so a pocket smaller than that can be missed or overstated.
