LIMPIA CREEK. Limpia Creek rises on the northeastern flank of Mount Livermore seventeen miles northwest of Fort Davis in central Jeff Davis County (at 30°38' N, 104°10' W) and runs northeast for sixty-three miles to its mouth on Barrilla Draw in western Pecos County (at 30°45' N, 103°29' W). Limpia Canyon, through which the creek runs for its first forty-two miles, was the principal avenue for early exploration and settlement of Jeff Davis County. Its upper reaches cross rugged terrain surfaced by shallow, stony soils that support Mexican buckeye, walnut, persimmon, desert willow, scrub brush, and sparse grasses. The lower reaches run through flat to rolling country surfaced by shallow, stony clay and sandy loams that support scrub brush, grasses, creosote bush, cacti, water-tolerant hardwoods, and conifers. Limpia is Spanish for "pure."
