It’s Our Fault!

Southern California San Andreas Geology Tour

Saturday, January 31, 2009 and
Sunday, February 1, 2009

Led by Dr. Donald Prothero, this day trip will explore the San Andreas fault from Palmdale to the Devil's Punchbowl, and see its effects on the entire region, including Vasquez Rocks. After a hike (optional) and picnic lunch at the Devil's Punchbowl State Park, we will drive over the top of the San Gabriel Mountains examining the evidence of their origin and evolution over 1.7 billion years. We will see remnants of giant billion-year-old magma chambers, and the products of rapid erosion of one of the fastest-rising mountain ranges in the world.
