Devils Postpile National Monument

Devils Postpile National Monument is located near Mammoth Mountain in eastern California's Sierra Nevada range. Managed by the National Park Service, this 798-acre area is highlighted by the Devils Postpile formation, a stunning display of columnar basalt that towers 60 feet high. This geologic marvel formed from volcanic lava cooling over 100,000 years ago, creating hexagonal columns that draw both geologists and tourists alike. The park is also home to the beautiful Rainbow Falls, where the San Joaquin River cascades down a 101-foot drop, creating vibrant rainbows in the mist. The region supports diverse flora and fauna, including pine forests, wildflowers, deer, and bird species, adding to its ecological richness. Popular activities include hiking, fishing, and photography, with trails offering panoramic views of the rugged landscape. Established in 1911, Devils Postpile continues to attract visitors for its natural beauty and recreational opportunities.
