The Precambrian and Paleozoic history of the Colorado Plateau is best revealed near its southern end, where the Grand Canyon has exposed rocks with ages that span almost 2 billion years. The oldest rocks at river level are igneous and metamorphic and have been lumped together as Vishnu Basement Rocks ; the oldest ages recorded by these rocks ...
View of Monument Valley in Utah, looking south on U.S. Route 163 from 13 miles (21 km) north of the Utah–Arizona state line Mitchell Mesa from the View Hotel.. Monument Valley (Navajo: Tsé Biiʼ Ndzisgaii, pronounced [tsʰépìːʔ ǹtsɪ̀skɑ̀ìː], meaning "valley of the rocks") is a region of the Colorado Plateau characterized by a cluster of sandstone buttes, with the largest reaching ...
Baker and Reeside revised Cross and Howe's work in 1929, tracing the Cutler across the Colorado Plateau and dividing the formation into the Halgaito Tongue, Cedar Mesa Sandstone Member, Organ Rock Tongue, and White Rim Sandstone Member. They also confirmed Cross and Howe's dating of the formation to the Permian. [21]
The Wingate Sandstone is a geologic formation in the Glen Canyon Group of the Colorado Plateau province of the United States which crops out in northern Arizona, northwest Colorado, Nevada, and Utah. Geology
The Colorado Province took shape as a mobile belt—an area of thinner, orogeny related continental crust lacking the deep "keel" of rock, which stabilized the neighboring Wyoming Craton and other cratons like it. Throughout Colorado's geologic history, rocks have often been deformed, metamorphosed and overprinted, obscuring the ancient record.
The Uncompahgre Plateau [1] in western Colorado is a distinctive large uplift part of the Colorado Plateau. Uncompahgre is a Ute word that describes the water: "Dirty Water" or "Rocks that make Water Red".
As in the Colorado Plateau, the lowest major unit in north-central New Mexico is a sandstone-rich member. This layer, the Agua Zarca Sandstone , [ 3 ] is often synonymized with the Shinarump Conglomerate, [ 22 ] [ 21 ] [ 19 ] though it may be derived from a different erosional source. [ 14 ]
The Navajo volcanic field is a monogenetic volcanic field located in the Four Corners region of the United States, in the central part of the Colorado Plateau.The volcanic field consists of over 80 volcanoes and associated intrusions of unusual potassium-rich compositions, with an age range of 26.2 to 24.7 million years ().
