Description

The dominant feature of the Wilderness is the high plateau from which the peaks arise. The plateau forms the northeastern portion of the White River Uplift capped by horizontal

The area contains approximately one hundred and ten ponds and lakes and is home to a wide variety of plants and animals, including many large mammals such as

. The highest point in the Flat Tops is the summit of Flat Top Mountain (12,361 ft) on the east side of the range. The Devil's Causeway, perhaps the most popular geologic feature and hiking experience in the Flat Tops, is located in the same area. The Causeway is a narrow neck of the plateau where eroding glaciers on either side almost met. A trail crosses the Causeway which at its narrowest is 3 to 4 feet wide with drop-offs of hundreds of feet to the valleys on either side. The eastern side of the Flat Tops Wilderness Area can be accessed by Routt County Rd 7 through the town of Yampa, Colorado. The best-known destination approached from the west side of the range is Trappers Lake.


History

The Chief of the U.S. Forest Service designated 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 The Wilderness Act of 1964 () is a federal land management statute meant to protect U.S. Wilderness Area, federal wilderness and to create a formal mechanism for designating wilderness. It was written by Howard Zahniser of The Wilderness Socie ...
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

On June 5, 1975, the Senate passed a bill sponsored by U.S. Senator Floyd Haskell (D-Colo.) to designate 235,230 acres as the Flat Tops Wilderness Area. The bill passed the U.S. House of Representatives by a vote of 369–1 on December 1, 1975, and was signed into law by President

In August 2002 two lightning-struck fires, the Big Fish and Lost Lake fires, burned more than 22,500 acres, almost 10% of the Wilderness Area.
