Get ready to learn about an area so complex that even geologists disagree about where the Siskiyou Mountains end and where the generally more recent Franciscan complex begins. We’ll go coastal from the Oregon/California border to 11 miles north of Brookings to find out when or if the Siskiyous stopped growing, why they are uplifting and moving north, and why the Far West has doubled in girth in the last half billion years. Find pillow basalts, clastic dikes, kinky folds, debris flows, and dirty sandstones in unmorphed mint condition.


Moderate (1-3 miles of hiking and/or climbs of up to 500 ft)


Ages 12+ are welcome.
