What to Do in Devils Postpile National Monument

Near Mammoth Lakes and surrounded by Inyo National Forest, Devils Postpile National Monument lies at an elevation of 7,560 feet in the eastern Sierra Nevada. The highlight of this 800-acre monument is a sheer wall of symmetrical basaltic columns more than 60 feet high. The formation is a remnant of a basalt flow worn smooth on top by glacial action. A trail leads to the top where the surface resembles a tile inlay.
