This is the first of two days of geologic field trips to the Northwest part of the Olympic Mountains. Jeff Tepper and Carol Serdar Tepper will lead a car-caravan trip with 24 participants to several West Coast beaches review the structure and stratigraphy of the area, much of which is comprised of deformed offshore sediments emplaced by subduction beneath the Olympic Mountains by the Cascadia subduction zone. There is no formal guide for the trip, but handouts will be distributed. See Day 2 of the trip (09-15-2013) to Hurricane Ridge.
