Abundant marine life can be found at some very popular dive sites on pilings. Titlow Beach Marine Preserve in Tacoma, Edmonds Oil Dock, Keystone State Park on Whidbey Island are but a few sites in Puget Sound that are great diver attractions. Titlow Beach in particular is used for conducting fish and invertebrate life training dives for REEF survey classes. (all photos by Janna Nichols, please credit if used)
