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 Okmulgee County's 697 square miles on soluble rock, 2 of them with the rock at or near the surface. With about 37,084 residents (53 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 319 map points about 1.5 miles apart, so a pocket smaller than that can be missed or overstated.
