GUAYULE CREEK. Guayule Creek rises a mile east of Pine Mountain in east central Brewster County (at 29°54' N, 102°48' W) and runs southwest for twenty-four miles to its mouth on Maravillas Creek, in the Black Gap Wildlife Management Area two miles northeast of Stillwell Mountain (at 29°40' N, 102°54' W). It traverses an area of steep to gentle slopes, surfaced by variable soils that support scrub brush and sparse grasses. In its lower reaches it passes through flat terrain with local deep and dense dissection, surfaced by shallow, stony soils that support oak, juniper, and some mesquite. Guayule is a plant used as a source of rubber. In the early twentieth century Brewster County seemed likely to become a major guayule rubber manufacturing center, but the supply of guayule proved insufficient, and the only factory actually built in the county operated intermittently for seventeen years before closing in 1926.
