What this means before you buy

Get a sinkhole or geotechnical inspection before buying, building or adding weight to a foundation.

That works out to roughly 256 of Loving County's 669 square miles on soluble rock, 256 of them with the rock at or near the surface. With about 48 residents (0 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 298 map points about 1.5 miles apart, so a pocket smaller than that can be missed or overstated.

Two things to read before deciding: why gypsum and salt move faster than limestone, and the signs to look for and how an inspection works.

Which formation it is

The largest mapped soluble unit here is the caliche deposits (evaporite), Pleistocene and Holocene in age, covering about 35% of the county. Next is the Dockum Group, undivided at 2%.

36% of the county sits on gypsum or salt, which dissolves in years rather than millennia. That share matters more than its size suggests.

The county also lies over the Permian Basin, Anadarko Basin,Dalhart Basin, Palo Duro Basin, a deep salt or gypsum basin. Deep beds rarely cause surface collapse on their own, but wells and mining into them have.

Loving County ranks 67 of 254 in Texas for soluble rock at the surface, and sits above 83% of US counties on that measure.
