November 1, 1973 - Elk hunters in extreme southwestern Gunnison County and northwestern Gunnison County and northeastern Hinsdale County should be alert for signs prohibiting motor vehicles in the newly established Powderhorn Primitive Area, according to Marlyn Jones, Montrose district manager for the Bureau of Land Management. “Department of Interior regulations prohibit motor vehicles in areas such as Powderhorn Primitive Area. So far the agency has found time to post only five signs informing hunters of the prohibition. Signs are located on the primitive area boundary on Indian Creek and the Ten Mile Springs. Three other signs are located two to three miles from the primitive area boundary on spur trails taking off from the long Gulch Truck Trail. The 40,500 Powderhorn Primitive Area, dedicated Sept. 29 by Interior Secretary Rogers C.B. Morton, is located primarily on the Calf Creek and Cannibal Plateaus at elevations up to 12,500 feet.
