Flat Tops Wilderness Area is the third largest U.S. Wilderness Area in Colorado. It is 235214acre, with 38870acre in Routt National Forest and 196344acre in White River National Forest. It was designated a wilderness area in 1975. Trappers Lake, located in the north of the area, was the lake that inspired Arthur Carhart, a United States Forest Service official, to plead for wilderness preservation.HistoryThe Chief of the U.S. Forest Service designated 118230acres of the Routt and White River national forests as the Flat Tops Primitive Area on March 4, 1932, to be managed to protect the area’s wild values.Congress passed the Wilderness Act in 1964, which, among other things, required the Secretary of Agriculture to review the suitability of all primitive areas for inclusion into the national wilderness system within ten years. Following this mandate, the U.S. Forest Service evaluated the Flat Tops primitive area and surrounding forest and in 1967 recommended 142,230 acres for wilderness designation.Conflict arose over the inclusion in the wilderness proposal of lands adjacent to the South Fork of the White River, near the southwest boundary of the proposed wilderness. Several private and public entities proposed dams and water diversions on the South Fork to facilitate development of rich oil shale deposits to the west. Timber interests also initially opposed designating wilderness outside the primitive area’s boundary.
