What to do about a house in Camas County

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

That works out to roughly 20 of Camas County's 1,074 square miles on soluble rock, 20 of them with the rock at or near the surface. With about 1,247 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 269 map points about 2.0 miles apart, so a pocket smaller than that can be missed or overstated.
