Abstract

The Lower Pecos region of Texas contains some of the most outstanding prehistoric rock paintings found in the New World. Covering the paintings is a natural rock crust that may play an important role in preserving these artifacts. We have determined that the rock crust is composed primarily of calcium oxalate in the mineral form whewellite. The origin of the whewellite is unknown.
