Uncompahgre National Forest is a U.S. National Forest covering 955,229 acres in parts of Montrose, Mesa, San Miguel, Ouray, Gunnison, Hinsdale, San Juan, and Delta Counties in western Colorado. Only its headquarters is in Delta County, in the city of Delta. It borders the San Juan National Forest to the south.
Within the national forest boundaries can be found the arid Uncompahgre Plateau and the northern portion of the San Juan Mountains. The forest contains three alpine wilderness areas: Uncompahgre, Mount Sneffels, and Lizard Head.
Uncompahgre National Forest was established on June 14, 1905. The Uncompahgre, Grand Mesa, and Gunnison National Forests were all administered separately until 1954 when Grand Mesa and Uncompahgre started to be administered as a single unit, with Gunnison added in 1973. Today, Uncompahgre National Forest is administered jointly with the Grand Mesa and Gunnison National Forests from the Forest Supervisor's Office in Delta, Colorado. There are local ranger district offices located in Montrose, Gunnison, and Norwood.
