BLACK HILLS CREEK
BLACK HILLS CREEK. Black Hills Creek rises near White Springs, seven miles northeast of the Black Hills in southeastern Presidio County (at 20°40' N, 104°01' W), and flows southwest for eighteen miles to join Terneros Creek. The united stream subsequently flows a mile to its mouth on the Rio Grande, four miles below Fort Leaton State Historic Site (at 29°32' N, 104°16' W). The stream principally crosses Quaternary alluvium, but it originates in volcanic deposits and terminates in the gravel terrace of the Rio Grande floodplain. The soils are light reddish-brown to brown sands and clay loams, often rough and stony. The vegetation consists primarily of sparse desert shrubs.
