Dixie National Forest in southern Utah, headquartered in Cedar City, is the state's largest national forest, covering nearly two million acres across about one hundred seventy miles along the divide between the Great Basin and the Colorado River country. Its elevation ranges from low desert near St. George to Blue Bell Knoll on Boulder Mountain, creating sharp contrasts in vegetation, climate, and scenery, including woodlands, high forests, cliffs, canyons, and hundreds of small lakes on Boulder Mountain. Established as the Dixie Forest Reserve in 1905, it became a national forest in 1907 and later expanded, remaining a major landscape for recreation, conservation, and wilderness protection.
