PALMA CANYON. Palma Canyon, a valley with an intermittent stream, begins in southeastern Terrell County (at 29°57' N, 101°59' W) a mile north of U.S. Highway 90 and four miles west of Cedar Station and runs southeast for eighteen miles to a point (at 29°49' N, 101°48' W) on Lozier Canyon, 3½ miles from where that canyon enters the Rio Grande, near the Val Verde county line. Cedar, Pony, and Cow creeks are tributaries. The canyon cuts through rolling prairies and flat terrain on chalk and wash deposits. Local soils are dark, calcareous, stony clays and clay loams, which support oaks, junipers, grasses, and water-tolerant hardwoods and conifers.
