Devil's Postpile Summer Retreat
August 07 - 10, 2014

Lake Ediza

The Place

Ansel Adams Wilderness encompasses 232,000 spectacular acres of granite peaks, steep-walled gorges and rock outcroppings. Several small glaciers cling to north and northeast facing slopes of the highest peaks. There are also a number of fairly large lakes on the eastern slope of the precipitous Ritter Range. Elevations range from 3,500 feet to 13,157 feet. The area includes approximately 350 miles of trails, including portions of the John Muir and Pacific Crest Trails.


Devils Postpile National Monument protects and preserves the Devils Postpile formation, the 101-foot high Rainbow Falls, and pristine mountain scenery. The formation is a rare sight in the geologic world and ranks as one of the world's finest examples of columnar basalt. Its columns tower 60 feet high and display an unusual symmetry.

Rainbow Falls

Pumice Flat is a group campground located near the San Joaquin River with easy access to trails in the Ansel Adams Wilderness and the Devil's Postpile. We will be at Group Site 2.
