Sinkhole risk in Carbon County, UT: No soluble rock mapped

The next step for one property

No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.

Across 1,479 square miles, under one square mile of Carbon County maps onto soluble rock. With about 20,613 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 345 map points about 2.1 miles apart, so a pocket smaller than that can be missed or overstated.
