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.

That works out to roughly 2 of Pike County's 545 square miles on soluble rock. With about 62,376 residents (114 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 472 map points about 1.1 miles apart, so a pocket smaller than that can be missed or overstated.
