Mt Jefferson WildernessThe Willamette National Forest has eight wildernesses which total 380,805 acres. These areas, the majority of which encompass seven major mountain peaks in the Cascades, are popular with hikers, backpackers, and mountain climbers. Maps are available for these areas.

The Forest Service began administering some of the National Forest System lands to preserve their primitive character as early as 1930. The Wilderness System was established by Congress in 1964 "for the use and enjoyment of the American people in such a manner as will leave them unimpaired for future use and enjoyment as wilderness." (The Wilderness Act, 1964)

These wildernesses exhibit evidence of the forces of nature, with the imprint of human work unnoticeable. They offer outstanding opportunities for solitude and primitive, unconfined recreation. Entry is by foot or horseback. Mechanized or wheeled equipment is prohibited.
