Baxter Pass is a high mountain pass at an elevation of 2.560m (8,400ft) above the sea level, located in Garfield County, in the U.S. state of Colorado. High-clearance 4WDs are recommended, though most stock SUVs are acceptable.
The road to the summit is unpaved (hard packed, sand and a few bumpy places and rocks larger than 6 inches). It’s called Co Hwy 201 (Baxter Pass Road). Not recommended to newbies. Along the way you’ll have to deal with some narrow parts with dangerous dropoffs: a short shelf road section on south approach. This is a rough dirt road through a really lonesome, isolated corner of Colorado. The winding and steep trail is accessible from June until October. The wind sometimes piled snow up as high as the windows of the passenger cars.
There are a few ghost towns along the way. The summit hosts a communication antenna. The pass is located on the way from Dragon (Utah) to Mack (Colorado). A railroad (Uintah Railway) once went up and over the pass to haul gilsonite from Dragon, Utah to Mack, Colorado. It was built during 1905-1906. The Uintah Railway was unique in that it was built for one product, and gilsonite supported it. During the 1920's and 1930's the advent of better roads and heavy trucks made the railroad obsolete, and it was finally abandoned in 1938.
