HORNICA CREEK. Hornica Creek rises about two miles northeast of Whiteflat in north central Motley County (at 34°08' N, 100°51' W) and runs northeast for eight miles to its mouth on the Pease River, ten miles southwest of Northfield (at 34°13' N, 100°44' W). The creek basin was near the northern boundary of the Matador Ranch in Motley County. Most of the surrounding region was considered average grazing land. The stream traverses an area of gently rolling hills with some moderately steep slopes, surfaced by shallow to moderately deep silt loams that support mesquite and grasses.
