Navajo Mountain (Navajo: Naatsisʼáán meaning "Earth Head"[3]) is a peak in San Juan County, Utah, with its southern flank extending into Coconino County, Arizona, in the United States.

[5] The Colorado Plateau is made of mostly flat-lying layers of sedimentary rock that record paleoclimate extremes ranging from oceans to widespread deserts over the last 1.8 billion years.

Following the military defeat of the Diné (Navajo people) by United States forces in 1863, the political landscape was changed by new boundaries and major physical alterations.

The establishment of Rainbow Bridge National Monument (1910), and the filling of Glen Canyon by Lake Powell in 1963, has facilitated tourism of this previously remote region.

Their descendants, the Hopi, call Navajo Mountain Tokonave, or "Heart of the Earth".
