Utah’s present geology has been greatly dictated by tectonic stresses that have occurred over the last 0.7 Ga. A determining factor in much of this Geology is the Hingeline that runs through Salt Lake County. Throughout the history of the western North America, this has been an important weak zone. It is no surprise that this same zone is now home to the Wasatch Fault System, which accommodates some of the extension of Western North America. The steep mountains facing west toward Salt Lake City were formed from the tectonic processes of the Fault. The Wasatch Fault is a normal fault, indicating that a hanging block (Salt Lake Valley) is moving downward along a hanging wall (Wasatch Mountains). The block’s movement is considered ‘stick slip’, which refers to the build-up and release of strain along the fault.
