Chapter 1: Introduction to Geology and Geomorphology of Eastern Santa Cruz Island, California

Jeffrey Mount

The Northern Channel Islands of California are part of the western Transverse Ranges. The islands are the surface expression of an extensive anticline produced by north-south shortening and east-west extension associated with the Big Bend of the San Andreas Fault. The geology and geomorphology of Santa Cruz Island, the largest of the Northern Channel Islands, records the complex history of the Transverse Ranges. This volume is a collection of papers developed during a Fall 2010 graduate seminar in Geology at the University of California, Davis. The class conducted a reconnaissance of the eastern end of Santa Cruz Island, contained within Channel Islands National Park. The volume contains papers on the tectonic history of the Transverse Ranges and the neotectonics of the Northern Channel Islands. In addition, papers explore the geology, marine terraces, stream profile development and hillslope processes of the eastern portion of the island. Finally, two papers examine the overall wave regime of the island and associated shoreline geomorphology.
