LEWIS CANYON. Lewis Canyon, a valley traversed by an intermittent stream, begins a mile southwest of Everett Ranch headquarters in central Val Verde County (at 30°02' N, 101°23' W) and runs southwest for nineteen miles to its mouth on the Pecos River, two miles above Shackelford Canyon (at 29°52' N 101°24' W). Its flow has sharply dissected massive limestone that underlies flat terrain, to form a rugged and winding valley. Wash deposits of sand, gravel, and mud cover the canyon floor. Soils of the area are generally dark, calcareous, stony clays and clay loams that primarily support oaks, junipers, grasses, and mesquites.
