California’s Eastern Sierra

Devil's Postpile National Monument

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. Not only does the Monument preserve and protect the fascinating formation of the Postpile, but it also serves as a portal to the sublime High Sierra backcountry. Over 90% of the Monument is designated as wilderness. Both the John Muir and the Pacific Crest Trails pass through the Monument.  A myriad of day-hikes and overnight trips originate from the Monument's trailhead.
