Devils Postpile National Monument in California is a striking geological formation known for its impressive columnar basalt formations. These hexagonal columns were formed over 100,000 years ago by cooling lava flows, creating one of the finest examples of columnar jointing in the world. The monument is located near the town of Mammoth Lakes in the Sierra Nevada and offers visitors opportunities for hiking, fishing, and camping. Additionally, the scenic Rainbow Falls, a 101-foot waterfall, is a popular attraction within the monument.
