OSO CREEK (PRESIDIO COUNTY)
OSO CREEK (Presidio County). Oso Creek rises near Chinati Peak in western Presidio County (at 29°57' N, 104°28' W) and flows southeasterly eight miles to its mouth on Cibolo Creek, 3½ miles east of U.S. Highway 67 (at 29°53' N, 104°20' W). Its course crosses desert mountain terrain, canyonland of volcanic deposits, rolling slopes of igneous rocks, and wash pediments of sand and gravels. The soils in the area are generally light reddish-brown to brown sand and clay loam, often rough and stony. The vegetation is primarily sparse grasses, cacti, and desert shrubs. Oso is Spanish for "bear."
