BARREL CANYON. Barrel Canyon, through which runs an intermittent stream, rises a mile east of Bullis Gap in eastern Brewster County (at 29°49' N, 102°35' W) and extends northeast for fourteen miles to its mouth on San Francisco Creek, five miles east of the junction of the Brewster-Terrell county line and the Rio Grande (at 29°53' N, 102°24' W). The terrain is flat with local shallow depressions and some deep, dense dissection. Soils in the area are clay and sandy loams and shallow, stony soils; they support water-tolerant hardwoods, conifers, and grasses, as well as oak, juniper, and some mesquite.
