Fort Worden

It seems like all my recent posts have been from the Strait - the Miller Peninsula, the Elwha, and now, the northeastern corner of the Quimper Peninsula. But recent is relative. This Saturday excursion to Fort Worden was back on the 10th, but if you've been paying attention the last ten years, you know that sometimes my posts run a bit late. Always in order, but often delayed. If you've been following along, you also know that my photos and my narrative don't always align terribly well.

The beach walk was part of a grand loop around the north side of Fort Worden. We began with low tide on the north side of Point Wilson, where we could look at the curiously distinct and squared off boulder field and the wood debris sticking out of the beach along its western edge. Bulldozers, faults, or coastal retreat across a back-barrier lagoon that used to sit below a steep forested slope? And how does that relate to the big divot in the bluff that looks so much like a singular landslide, but which doesn't explain why the coastline itself jogs as well.

AERIAL VIEW

The beach along North Beach is great, with sand, gravel, big boulders, and occasionally glimpses of the underlying platform. But it's somewhat overshadowed - figuratively and literally - by the bluffs themselves. At the eastern end, it looks like Whidbey Formation, including a surprisingly continuous peat layer a few feet above beach level, overlain by Vashon stuff. But as you move west, the layer cake has been disturbed and late glacial Everson (so I'm told) appears - mainly gravels, but with some amazing ripups of the underlying glacial material. Something pretty exciting happened here during the waning stages of the last glaciation - it took a lot of water moving very fast to leave that kind of deposit (and it's much better exposed than my last visit). Is this evidence of Puget Sound (Lake Russell?) spilling out around the edge of the retreating ice? Or something else.

The walk back along the top edge of the bluff was a lesson in periodically relocated fence lines on the bluff (always to the south) and big artillery (the big guns are all gone, but the batteries and the views remain).
