Granite Mountain (Utah) Granite Mountain (Utah) Granite Mountain is a mass of solid rock one mile up Little Cottonwood Canyon in the Wasatch Range of Utah, not too far from Salt Lake City, Utah. Despite its name, Granite Mountain is primarily composed of quartz monzonite, an igneous rock similar to granite in appearance, physical characteristics, and chemical composition. This is the same material used to construct the Salt Lake Temple and the facade of the LDS Conference Center. The Granite Mountain Records Vault (also known simply as The Vault) is a large archive and vault owned by The Church of Jesus Christ of
Granite dome on erosional offloading or pressure release. There is evidence that supports this hypothesis when looking at granitic landforms that have sheet fractures. Granite forms deep in the Earth’s crust under conditions of high ambient or lithostatic pressure. In order for the granite to be exposed at the Earth’s surface a considerable thickness of rock must be eroded. This unloading allows the granite to expand radially and sheet fractures form tangentially to the radial stress. This indicates that the shape of the pre-existing land surface determines the geometry of the sheet fractures. One hypothesis is that granite domes are uplifted blocks.
