Updated trip to Nodule Point & Liplip on Marrowstone Island

For whatever reason, the webpage describing the geology at Nodule Point on Marrowstone Island (south of Port Townsend) has received a lot of visits lately. I decided to see what I’d written back in the fall of 2010. I found that somehow I had deleted the photographs. I have replaced those with the originals from Dan McShane, or new ones provided by Bob and Adena Mooers, who field-checked the original trip. The trip describes latest glacial deposits, cannonball-like concretions, and best of all for this volcanophile, a basalt dike intruding the sandstone bedrock.

Visit the webpage here.
