YELLOW WOLF CREEK. Yellow Wolf Creek rises in the Parramore oilfield in southwest Nolan County (at 32°09' N, 100°33' W) and runs southwest twenty miles into north central Coke County. The creek basin area was settled during the 1880s and used primarily for ranchland. An Indian chief, presumably buried in the area, provided the creek's name. The intermittent stream passes near Horse Mountain (elevation 2,518 feet) and flows through Sanco to its mouth on the E. V. Spence Reservoir, seven miles northwest of Robert Lee (at 31°50' N, 100°35' W). The area is mostly flat to rolling, and hardwoods and grasses grow in moderately deep to deep sandy and clay loam.
