Not true karst, but soil piping or lava tubes can still open voids - mention it to an inspector.

Across 924 square miles, under one square mile of Rusk County maps onto soluble rock. With about 53,391 residents (58 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 1.7 miles apart, so a pocket smaller than that can be missed or overstated.
