Rising 867 feet, this igneous monolith is the first U.S. national monument. Considered sacred by Indigenous tribes, it is composed of a rare rock called phonolite porphyry. The vertical fluted columns attract geologists, climbers, and visitors alike. Geologists believe it formed from magma intrusion millions of years ago. Today, this geological anomaly is a symbol of the American West.
