The burned remains of a tractor-trailer on U.S. Highway 550 north of Durango caught the attention of passing drivers Monday. The truck crashed Thursday night at the base of Coal Bank Pass near the hairpin turn at Cascade Creek. The driver suffered moderate injuries. Colorado State Patrol Capt. Adrian Driscoll said a hazmat team cleaned up spilled diesel fuel at the site. The truck was hauling gilsonite, which is used as a road base for asphalt and is not considered hazardous.
