Caption Wyoming - Sherman Mountains - The Sherman Mountains are erosional remnants rising above the general level of the surface of the Laramie Range. The flat topped characteristic of the range resulted from beveling during an ancient erosion cycle. Bedrock here is granite, a crystalline rock made up of pink feldspar, glassy quartz, black mica and hornblende, which originated deep in the earth's crust over a billion years ago. the peculiar rock forms of the Dherman Mountains are controlled by three sets of joints or planes of weakness cutting the granite and dividing it into large blocks. Weathering has rounded off corners and has enlarged joints planes, resulting in irregular blocky rock masses, many of which are capped by balanced rocks.
