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 Granite dome Granite domes are domical hills composed of granite with bare rock exposed over most of the surface. Generally, domical features such as these are known as bornhardts. Bornhardts can form in any type of plutonic rock but are typically composed of granite and granitic gneiss. As granitic plutons cool kilometers below the earth’s surface, minerals in the rock crystallize under uniform confining pressure. Erosion brings the rock closer to earth’s surface and the pressure from above the rock decreases; as a result the rock fractures. These fractures are known as exfoliation joints, or sheet fractures, and form in
