What to do about a house in Morrow County
No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.
Across 2,031 square miles, under one square mile of Morrow County maps onto soluble rock. With about 12,360 residents (6 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 307 map points about 2.6 miles apart, so a pocket smaller than that can be missed or overstated.
