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.

Wolf Creek Pass, once a two-lane road winding through the San Juan Mountains between South Fork, Colorado, and Pagosa Springs, has been expanded into a multi-lane highway, greatly increasing the traffic capacity of the pass and making it more navigable in bad weather. It is the easiest access to southwest Colorado from the rest of the state, as all remaining overland routes require lengthy detours through New Mexico or over Lizard Head Pass, near Telluride, or the intimidating Red Mountain Pass, a two-lane road winding along sheer cliffs from Ouray to Silverton.

History

According to historical documents, the creation of the first road along Wolf Creek Pass began in 1911 and finished construction in 1916. The project's engineers were J. E. Maloney and Ed Riley. The 12 feet wide road was doubled in width in 1930 and was paved 20 years later.

A 900-foot (270 m) tunnel on the eastern portion was opened November 5, 2005. Construction was completed in the Summer of 2006, with the highway fully widened and drainage projects along the route completed.

Attractions

The Lobo Overlook, at 11,760 feet elevation on the north side of the pass, provides commanding views of the continental divide.

The pass is also home to Wolf Creek ski area located on the eastern side of the Continental Divide on Highway 160. Also on the eastern side is one of the largest RV parks in the United States, located just a few miles west of South Fork, Colorado.

Wolf Creek Pass is also an attraction for tourists, as it is known for the natural beauty of the wilderness the highway passes through. Just west of the pass, Treasure Falls offers passersby a view of a mountain waterfall.

Name

The pass was named for Wolf Creek, which starts near the top of the pass and flows down its western side to a confluence with the West Fork San Juan River in Mineral County.

C. W. McCall

Wolf Creek Pass was made famous in 1975 by country music artist C. W. McCall's spoken word song of the same name, in which the pass is described as "37 miles o' hell – which is up on the Great Divide." The song describes the truck careening down through a "tunnel" (during which process several crates of chickens stacked on the back of the truck are inadvertently lost) and eventually into a feed store in Pagosa Springs.

Climate

Wolf Creek Pass has a subarctic climate (Dfc) with substantial precipitation year round, though it may be called a subalpine climate due to it having a different climate than other climates on a similar latitude due to its high elevation. Summer usually consists of mild days and chilly nights. Winter consists of cold days with nightly lows close to zero lasting from early November to sometimes into April. Annual snowfall is heavy, averaging 435.6 inches (1,106 cm), one of highest in the entire state, usually beginning by late September and not ceasing until sometimes early June. March averages the highest snowpack of the year at 67 inches 170.2 cm).
