NORTHRUP CREEK. Northrup (or Northrun) Creek rises (at 36°06' N, 100°47' W) just north of Farm Road 281 in southern Ochiltree County and runs northeast for eleven miles to its mouth (at 36°13' N, 100°38' W) on Wolf Creek, just downstream from Lake Fryer. The local terrain is flat to gently sloping and surfaced by loose sand that supports scrub brush and grasses. The Jones and Plummer Trail crossed the upper waters of the stream, which was once part of the Bar CC ranges.
