Uncompahgre National Forest spans 955,229 acres in western Colorado across plateau and mountain terrain in several counties, with administration centered in Delta. Established on June 14, 1905, it later became jointly managed with the Grand Mesa and Gunnison national forests. Its landscape combines the dry Uncompahgre Plateau with the northern San Juan Mountains and includes the Uncompahgre, Mount Sneffels, and Lizard Head wilderness areas. Known for scenic drives, hiking, jeep and ATV travel, and routes that trace old mining roads, it also preserves notable natural history, including the West Gold Hill Dinosaur Tracksite with 134 fossilized sauropod footprints.
