The United States Congress designated the Rogue-Umpqua Divide Wilderness (map
) in 1984 and it now has a total of 35,749 acres
All of this wilderness is located in Oregon
and is managed by the Forest Service.
The Rogue Umpqua Divide Wilderness is located in southwest Oregon, ten miles west of Crater Lake National Park. Elevations range from 3000 to 6800 feet along the divide between the Rogue and Umpqua Rivers. Geologic history has created many unique volcanic and sedimentary rock outcrops. Dense conifer forest gives way to a mosaic of big trees and sub-alpine meadows in the higher elevations. Meadow wildflowers are abundant in summer and diverse plant communities provide habitat for everything from hummingbirds to black bears. Water is abundant in streams and a handful of lakes. About 100 miles of trails access the area, providing loop opportunities and ridgetop vistas. Snow accumulations are transitory below 4000 feet and the entire area is usually snow free by mid-July.
