* Due to the tree and rock fall, erosion and other hazards caused by the 2020 fire in the Ice Lakes and South Mineral Creek Rd area the forest in this area has been closed by the Columbine Ranger District for the summer of 2021. The Silverton Ultra Dirty has been granted special permission for the aid station crews to access Bandera Aid Station which is at the southern terminus of S. Mineral Creek Rd. This closure prohibits any spectators, crews and pacers to access Bandera Aid Station. This means the 60K will not be allowed to have pacers.
