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.

Across 748 square miles, under one square mile of Karnes County maps onto soluble rock. With about 15,137 residents (20 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 540 map points about 1.2 miles apart, so a pocket smaller than that can be missed or overstated.
