GLENN DRAW. Glenn Draw, through which runs an intermittent stream, is also known as Glenn Spring Draw. It begins just southwest of Chilicotal Mountain and a mile northwest of Glenn Spring in Big Bend National Park in southern Brewster County (at 29°11' N, 103°10' W) and extends southeast for ten miles before opening on the Rio Grande at Compton's fishing camp, twelve miles southwest of Boquillas (at 29°06' N, 103°05' W). Compton's is named for C. G. Compton, a local storekeeper whose son was killed in a raid by Mexican bandits in 1916. Glenn Draw crosses variable terrain surfaced by soils that support scrub brush and sparse grasses. In its lower reaches shallow, stony clay loams support juniper, oak, grasses, chaparral, and cacti. The draw, like the spring, was named for W. J. Glenn, who surveyed the area in 1881.
