What this means before you buy

Sinkholes are uncommon here; watch for new depressions after heavy rain or leaking pipes.

That works out to roughly 37 of Montague County's 931 square miles on soluble rock, 37 of them with the rock at or near the surface. With about 21,890 residents (24 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 346 map points about 1.6 miles apart, so a pocket smaller than that can be missed or overstated.
