Smith Draw joins Horsehead a mile west of the Pecos. Horsehead Draw crosses an area of rolling terrain and steep to gentle slopes over caliche and alluvial sand, gravel, and mud. The soils vary from rough, stony ground to light reddish-brown to brown sands and clay loams.
Local vegetation includes scrub brush, sparse grasses, creosote bush, and cacti.
Horsehead Draw was likely named by the early Indians who inhabited the area. The Handbook of Texas Online. The Texas State Historical Association, 1997,1998,1999.
