KELLOGG CANYON. Kellogg Canyon, which has an intermittent stream, rises four miles southwest of Bullis Gap and twelve miles northeast of Dove Mountain in eastern Brewster County (at 29°48' N, 102°40' W) and runs northeast for thirteen miles, passing through Bullis Gap before reaching its mouth on San Francisco Creek, six miles northeast of Bullis Gap and a mile northeast of the San Francisco Creek Ranch (at 29°53' N, 102°32' W). It traverses flat terrain with local shallow depressions, surfaced by clay and sandy loams that support water-tolerant hardwoods, conifers, and grasses.
