Monument Valley near Oljato in the United States is a high desert basin where sandstone towers stand above a broad rust-coloured plain on Navajo Nation land. The valley straddles the Arizona–Utah state line and forms part of Monument Valley Navajo Tribal Park, established as a protected area in the mid-twentieth century.
Sandstone towers on the Colorado Plateau
Monument Valley lies on the south-western edge of the Colorado Plateau, in San Juan County in Utah and Navajo County in Arizona, with the Navajo settlement of Oljato-Monument Valley nearby.Arizona–Utah border within the Navajo Nation The land is formally designated as Monument Valley Navajo Tribal Park rather than any national park, and it lies entirely within the sovereign territory of the Navajo Nation.Monument Valley Navajo Tribal Park
From the valley floor, sandstone buttes and mesas rise in sheer cliffs from low slopes of softer rock, giving the basin its distinctive skyline. Many of the towers are erosional remnants of a once more continuous plateau, consisting of lower slopes of Organ Rock Formation, vertical cliffs of De Chelly Sandstone and an upper caprock of Moenkopi and Shinarump units that slows the retreat of their tops.erosional buttes and mesas The combination of a flat plain and isolated stone towers gives Monument Valley a recognisable profile in wide views across the desert.
A Navajo Tribal Park and Diné landscape
Monument Valley is administered as a Navajo Tribal Park, established by the Navajo Nation’s tribal council in 1958 to protect both the landforms and their cultural significance.Tribal Park established 1958 The protected area spans 91,696 acres across the Arizona–Utah border and is marked on maps as Monument Valley Navajo Tribal Park, with administration based at Oljato-Monument Valley.protected Navajo Tribal Park
The Navajo name Tsé Bii? Ndzisgaii, sometimes translated as “valley of the rocks”, points to the relationship between the broad sandy basin and the stone forms rising from it.Tsé Bii?

Geology and the making of the valley floor
Geologically, the rock layers exposed in Monument Valley range from Permian to Triassic in age and form part of a thick sequence of sedimentary formations on the Colorado Plateau.Permian rocks of Monument Valley The lower slopes of many towers are carved from Organ Rock Shale, which weathers into red surfaces, while the cliffs above consist largely of De Chelly Sandstone, a windblown sandstone of Permian age that once formed part of an extensive dune field.Permian De Chelly Sandstone
Above the De Chelly Sandstone, resistant layers such as the Shinarump member of the Chinle Formation and Moenkopi Sandstone cap many mesas and buttes, protecting their tops from rapid erosion.Moenkopi and Shinarump caprock On the valley floor, sand and siltstone stained with iron oxide form broad plains known as Cedar Mesa Sandstone, giving the basin its characteristic red surface visible in distant views.Cedar Mesa Sandstone valley floor The combination of hard caps and softer lower units underlies the contrast between vertical towers and low eroded slopes that defines the valley’s form.
