Offset stream channel in Carrizo Plain

Stream channel offset right-laterally by the San Andreas fault at Wallace Creek in the Carrizo Plain. (ID 5D-11396)

Wasatch Mtns, E edge of Basin-Range

The eastern edge: Mt. Timpanogos, in the Wasatch Range of Utah. Mt. Timpanogos is the second highest peak of the Wasatch Range, at an elevation of 11749'. The Wasatch Range rises along the Wasatch fault, which is an active fault, and so poses a significant earthquake hazard to the Salt Lake City region. As evidence of recent faulting, two wineglass canyons can be seen behind the fault on the right side of the photo. (ID: 477-89)
