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

Across 2,667 square miles, under one square mile of Itasca County maps onto soluble rock. With about 45,442 residents (17 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 308 map points about 2.9 miles apart, so a pocket smaller than that can be missed or overstated.
