Bullman Beach
I hadn't been this far out the Strait for years, and then two trips in about a month. This particular morning I caught the 5:30 Edmonds ferry and made it to Bullman's by 9AM.
The shoreline out here is rocky, with beaches located only where some combination of shoreline configuration and local sediment sources conspire. Bullman's is a half a mile of pocket beach fed largely, as far as I can tell, by the stream that emerges in the middle. A rocky promontory at the eastern end keeps the waves coming in the Strait from spilling sand out that end. As with any pocket beach, it's orientation probably tells us as much about the angle of wave action on this beach as any sophisticated model would.
Kelp was washed up in berms at the west end, pushed against sandstone boulders that looked almost like highway department riprap (but for the most part, were not).
The backshore grades landward to meet the filled areas around the homes. This end of the Olympic Peninsula is being pushed up faster than sea level is rising (at least during the past century, but maybe not the next), so I'm guessing the shoreline is gradually marching seaward. But I wonder what the story with those huge stumps in the back beach near the west end - did they wash in (how?), or are they in growth position -- which might really complicate the story.
