Monument Valley in Oljato, USA, is a Navajo Tribal Park on the Arizona–Utah border, defined by sandstone towers rising above a broad desert plain. Its buttes and mesas stand within Navajo Nation land, where the valley’s Navajo name Tsé Bii? Ndzisgaii refers to a valley of rocks shaped over geological time.Tsé Bii? Ndzisgaii
Sandstone buttes, mesas and the Colorado Plateau
The landscape of Monument Valley sits on the Colorado Plateau, a high region of layered sedimentary rocks spanning parts of Utah and Arizona. Within the valley, sandstone buttes, mesas and slender spires rise above the surrounding floor, forming a concentration of isolated rock monuments that have become visual shorthand for the desert Southwest.sandstone buttes, mesas and spires
Geologically, the valley’s towers and plateaus are carved from Permian and Triassic sandstones and related sedimentary layers, part of a long stratigraphic stack that underlies the Colorado Plateau.permo-triasic sedimentary formations The cliffs in Monument Valley are largely formed by massive De Chelly sandstone, while gentler slopes below them include the Organ Rock formation. Together these units create a stepped profile, with tougher caprock protecting softer layers that erode into slopes and benches.
A Navajo Tribal Park on the Arizona–Utah border
Monument Valley lies in both San Juan County in Utah and Navajo County in Arizona, straddling the state line in an area managed as Monument Valley Navajo Tribal Park.San Juan County, UT and Navajo County, AZ The park sits within the Navajo Nation rather than any state or national park system, and the surrounding settlement is known as Oljato-Monument Valley.
The tribal park covers an area of Navajo land where sandstone formations rise above an arid plain at an elevation of more than 1,600 m (5,564 ft) above sea level.5,564 feet above sea level The Navajo Nation designates Oljato itself as a chapter area with a land area counted in hundreds of thousands of acres, and the park lies within this broader unit.Oljato chapter land area
Reading the desert: mesas, buttes and named rock formations
Within the valley, mesas form broad-topped plateaus with steep sides, while buttes represent a later stage of erosion where the remnant hill becomes taller than it is wide. In Monument Valley, many of the most recognisable towers are buttes, isolated sandstone hills with vertical faces and flat tops rising high above the desert floor.sandstone buttes
Individual formations carry descriptive names passed into English, including the East and West Mitten Buttes and Merrick Butte, which stand close to the main valley floor.East and West Mittens and Merrick Butte A larger plateau, Sentinel Mesa, marks a central mesa that overlooks much of the front of the park and is regarded in Navajo tradition as one of the door posts to the valley.Sentinel Mesa as a door post
