ROBERTSON CREEK. Robertson Creek rises immediately west of State Highway 1170 one mile southeast of Maryneal in south central Nolan County (at 32°13' N, 100°27' W) and runs southeast for thirteen miles to its mouth on Oak Creek, two miles northwest of Blackwell (at 32°07' N, 100°20' W). The surrounding flat to rolling terrain has steep margins and moderately steep slopes with high local relief and is surfaced by marl and sand that support juniper, liveoak, mesquite, elm, and grasses.
