Kebler Pass is a high mountain pass at an elevation of 10,007ft. (3.050m) above the sea level, located in Colorado, USA. The pass links highway 133 (close to Somerset) and Crested Butte. The road is gravel and closed during the winter months.
The speed limit is 30 mph. The grades on the highway are very gentle. The surface on this gravel road is often loose, especially along the sides of the road. It makes necessary to drive carefully and slow down whenever approaching an oncoming car.
In summers, the road is accessible by all passenger vehicles. The Colorado Department of Transportation refers to this road as GCR 12. The quality of the road is very good and easily driven by any passenger vehicle. It is a two-lane graded (ie smooth) dirt road with a dust inhibiting coating. With the coating, probably magnesium chloride or calcium chloride, the road is very smooth and almost as good as a paved road. A few portions of the road near the top of the pass have been paved.
