The West Coast of North America has, possibly, the most complicated geological history in the world. Multiple collisions of small continents and island arcs over hundreds of millions of years have shaped the large mountains and islands we can see from North Beach. Large faults run between Whidbey Island and the Quimper Peninsula, and along the Strait of Juan  De Fuca.

At a smaller scale the glaciations of the last few million years
shaped the Port Townsend area where the bluffs, and the shoreline tell
us yet another story. We also layer (pun intended) in the history of
sea level change.

Our February Outing will focus on some of the broader aspects of the
geological history of the area and invite you to ask questions of the
features large and small that we will see as we walk from Battery
Kinzie to North Beach.
