Nisqually Reach

We took the class back to Tolmie this year. It's a good beach walk - especially on a nice June day. Bluffs, bulkheads, and a nice little barrier estuary. And some weird geology.

Two years ago (Butterball Cove), I was intrigued by the presence of a resistant geologic unit right below the surface of the beach. This year, the beach is lower, and this band of rock was much better exposed. I'm not sure what is most intriguing, the ledge, or the fact that the beach has fallen several inches. Between the geology of the site and the amount of bulkheading in the vicinity, its not like there's very much new sediment available to replace what gets lost.
