What to do about a house in Gilliam County
No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.
Across 1,205 square miles, under one square mile of Gilliam County maps onto soluble rock. With about 1,971 residents (2 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 243 map points about 2.2 miles apart, so a pocket smaller than that can be missed or overstated.
