WALKER CANYON CREEK. Walker Canyon Creek rises ten miles north of Matador in north central Motley County (at 34°08' N, 100°46' W). The intermittent stream is an important source of Hornica Creek, which it joins (at 34°11' N, 100°46' W) after a northerly journey of six miles. The area was a part of the Matador Ranch and is average grazing land. Walker Canyon Creek flows through moderately steep slopes with locally high relief, surfaced by shallow to moderately deep silt loams that support mesquite and grasses. Its confluence with Hornica Creek is eleven miles northeast of Whiteflat.
