Established in 1911 by Presidential proclamation, Devils Postpile National Monument (located near Mammoth Mountain in California) 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.
