Navajo Mountain is a towering isolated peak on the Navajo Nation in southeastern Utah, extending into northern Arizona, and at about 10,388 feet it is the Nation’s highest point. Geologically, it is a free-standing laccolith whose igneous core pushed up surrounding sedimentary layers, later exposed by erosion. Its slopes reveal several major rock formations, and its summit is uplifted Dakota Sandstone from the Cretaceous Period. The mountain holds deep importance in the traditions of the Diné, Hopi, and San Juan Paiutes. Despite twentieth-century boundary changes and rising tourism, it remains a protected sacred landscape under Navajo Nation regulation, also known for rare high-elevation plant life.
