DOCKUM CREEK. Dockum Creek rises by Farm Road 836 a mile from the Crosby-Dickens county line in east central Crosby County on the eastern edge of the Caprock (at 33°39' N, 101°03' W) and runs southeast for eighteen miles, forming the northern city limit of Spur before reaching its mouth on Duck Creek, in southwest Dickens County (at 33°29' N, 100°50' W). It traverses flat to moderately steep terrain surfaced by clay, sand, and silt loams that support grasses, scrub brush, mesquite, and cacti. This region was the first part of the county to be settled, when homesteaders moved to the area in the late 1870s. It was named for W. C. Dockum, a buffalo hunter who established a store and post office in the area.
