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

Across 1,545 square miles, under one square mile of Marathon County maps onto soluble rock. With about 139,091 residents (90 per square mile), homes are spread across towns and farmland, and a mapped unit may or may not reach the developed parts. The figures come from 407 map points about 1.9 miles apart, so a pocket smaller than that can be missed or overstated.
