The Brothers Wilderness

Area Status: Open
The Brothers Wilderness.

The Brothers Wilderness is located on the east side of the Olympic National Forest, north of Lena Lake in Jefferson County. Except for a relatively gentle valley area in the East Fork of Lena Creek, the entire 16,682 acre Wilderness is quite precipitous with tree covered slopes extending to about 5,000 feet. Elevation ranges from 699 feet near the Dosewallips River to the 6,866 foot summit of The Brothers. Other major peaks include Mt. Jupiter Ridge, and St. Peter's Dome. Western hemlock, Douglas-fir and western red cedar dominate the lower slopes. Pacific silver fir and mountain hemlock cover the upper slopes before giving way to subalpine fir and mountain meadows and rock outcrops.

The Duckabush River is the only major stream flowing through the Wilderness. Jupiter Lakes and several small ponds are located on Jupiter Ridge.

Please follow regulations and use Leave No Trace techniques to help protect this unique area.
