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

Across 572 square miles, under one square mile of Mille Lacs County maps onto soluble rock. With about 27,577 residents (48 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 325 map points about 1.3 miles apart, so a pocket smaller than that can be missed or overstated.

Two things to read before deciding: how these percentages are measured, and the warning signs that apply anywhere.
