TERNEROS CREEK. Terneros (also spelled Torneros) Creek rises south of Tascotal Mesa in southeastern Presidio County (at 29°34' N, 103°50' W) and flows west across the Alazan Hills, along the Tascotal fault zone, and then southwest for twenty-six miles to join Black Hills Creek. The united stream flows 1½ miles to its mouth on the Rio Grande, 4½ miles below Fort Leaton State Historic Site (at 29°31' N, 104°16' W). The course of Terneros Creek crosses the volcanic intrusives and flows of the Alazan Hills and the Bofecillos Mountains areas and flows over a Quaternary alluvium for half of its length before terminating in the gravel terrace of the Rio Grande floodplain. The soils in the area are light reddish-brown to brown sands and clay loams, often rough and stony. The vegetation consists primarily of sparse desert shrubs. Terneros Creek was probably named for the ranch by the same name on its banks.
