	GSA Wallace Creek Field Guide (Geological Society of America Centennial Field Guide, Cordilleran Section, 1987)   This field guide provides a more in-depth tour of the same 2-km stretch of fault described in the Interpretive Trail guide.  It is designed for those with some geological background and describes a number of features not mentioned in the Interpretive Trail guide.  It also explains how geologists were able to determine that this section of the fault has not moved since the last big earthquake, in 1857.
