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. The following, adapted from the Chicago
