I've been to the Marine Science Center's Geology Exhibit several times -- I recommend it as an excellent primer for learning about local geology: glaciers, plate tectonics, local fossils, ice-transported rocks (erratics) and beach sand. The gift shop sells an excellent fold-open water-proof guide for beach pebble identification.
Later, we visited Tamanowas Rock. This monolith is a sacred S'Klallam site in Chimacum, now under Jefferson County Land Trust preservation. The honeycomb (geology speak = tafoni) weathering pattern give the cliffs a very interesting texture. A volcanic block and ash flow eruption 30 million years ago created deposits of dacite/adakite composition. The trail is very steep, so be prepared. Dr. Jeff Tepper gave a great lecture on Tamanowas Rock Saturday June 11 http://www.saveland.org/Events/Event_Detail.aspx?processID=81
On the hike out, I saw several gorgeous foxgloves. Spring is here -- and with only a week left -- just in time.
