What this means before you buy
No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.
Across 3,973 square miles, under one square mile of Chouteau County maps onto soluble rock. With about 5,880 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 299 map points about 3.6 miles apart, so a pocket smaller than that can be missed or overstated.
