PIÑON HILLS. The Piñon Hills are immediately east of the Delaware Mountains and a mile south of Guadalupe Pass in northwestern Culberson County (with a center point of 31°48' N, 104°46' W). They stretch six miles to the southeast, parallel to the Delawares. The highest elevation in the Piñon Hills is 5,595 feet above sea level. The steep, rocky hills are surfaced by shallow, stony soils that support live oak, juniper, grasses, and the piñons for which the hills are named.
