I have always been fascinated with this cliff in Little Cottonwood Canyon, outside of Salt Lake City, Utah. Almost all of the other rocks in the area are quartz monzonite commonly called granite. This cliff is in the Deseret Limestone and Gardison Formation and is often referred to as marble and is composed of a metamorphic white limestone. This formation is the location of most of the silver mines located in and around Alta. The cliff is on the north side of the canyon just as you reach the ski resorts.
