In 1908, the Deschutes National Forest was established from parts of the Blue Mountains, Cascade, and Fremont National Forests. Nestled along the Cascade Mountains, the Deschutes National Forest is one of the most popular recreation forests in the Pacific Northwest. Truly a four season vacationland, the Forest attracts more than 8 million people every year to camp, climb, fish, hike, hunt, ski, and enjoy a multitude of outdoor activities.

Three Sisters Wilderness area covers 286,708 total acres. There are approximately 260 miles of trail within the wilderness. The Pacific Crest National Scenic Trail traverses the wilderness for 40 miles. Most trails entering the wilderness begin in dense forests of Douglas-fir on the western slopes of the Cascades and ponderosa pine on the eastern slopes.

The major peaks are the North, Middle, and South Sisters (all above 10,000'), along with Broken Top, the best example in the Pacific Northwest of the effect of glaciation. Collier Glacier is the largest glacier in Oregon. Other geologic features include Rock Mesa, Collier Cone, and Yapoah Crater. Alpine meadows, waterfalls, lava fields, glaciers, and glacial lakes are abundant. Fish populations include brook and rainbow trout. Forest in this Wilderness consists mainly of Douglas-fir, silver fir, sub-alpine fir, mountain hemlock, western hemlock, true fir, lodgepole pine, and ponderosa pine. Alpine meadows are abundant.

Our volunteer group will assist the Forest Service with several much-needed projects including trail work, fire ring removal, campsite restoration and the installation of trail and campsite signage. We will hike in on the Green Lakes Trail, following the beautiful Falls Creek to its junction with the Moraine Lake Trail which will lead us to camp. The total distance is about 4 miles. Our camp will be at the gorgeous Moraine Lake with a splendid view of the South Sister to our north. This trip will also have pack support.

Possible free day activities include hiking to the summit of South Sister (8 miles RT, difficult), hiking to the Green Lakes (8 miles RT, moderate), hiking Wickiup Plain (6 miles RT, easy), swimming, wildlife observation, photography, etc.

This project is rated as a strenuous project.
