Desolation Peak Lookout was also established by the Forest Service on the Mount Baker National Forest and later transferred to the North Cascades National Park. The 14' x 14' L-4 ground house without catwalk was built in 1933 and remains active under the NPS. Accessible by trail 23 miles from the nearest road, or 13 miles up Ross Lake and then 7 miles of trail, it is one of the most remote active lookouts in the U.S.
