BIG SATAN CREEK
BIG SATAN CREEK. Big Satan Creek rises 2½ miles west of U.S. Highway 277/377 in east central Val Verde County (at 29°44' N, 100°51' W) and runs southwest for thirteen miles to its mouth on the Devils River, here part of Amistad Reservoir (at 29°40' N, 100°57' W). The last part of the streamcourse passes through Satan Canyon. Bluff Creek is a tributary. The path of Big Satan Creek sharply dissects massive limestone that underlies flat terrain, forming a deep and winding canyon. The area's generally dark, calcareous, stony clays and clay loams support oaks, junipers, grasses, and mesquites.
