Granite Knob
This granite knob lies in the Sweewater Rocks in the Granite Mountains near Jeffery City, Wyoming. Geologically, this granite knob is located in the Archean-age Sweetwater subprovince of the Wyoming Craton. These rocks represent a time when Wyoming was a separate microcontinent called the Wyoming Craton which existed 500 million years before the North American Continent formed. The Sweetwater subprovince has an east-west tectonic grain which is caused by a shear zone between the Sweetwater and Southern Accredited Terrane subprovinces along the southern edge of the Wyoming microcontinent.
