Wolf Creek Pass is a high mountain pass on the Continental Divide, in the San Juan Mountains of Colorado. It is the route through which U.S. Highway 160 passes from the San Luis Valley into southwest Colorado on its way to New Mexico and Arizona. The pass is notable as inspiration of a C. W. McCall song. The pass is significantly steep on either side (6.8% maximum grade) and can be dangerous in winter. There are two runaway truck ramps on the westbound side for truckers that lose control of their brakes.
