17. Vashon Island, Puget Sound  This morph is from dock pilings in Paradise Cove on the west side of the island.  The author writes:  “As is commonly seen in such conditions, the piles are covered by an extensive growth of marine organisms, which appear to supply the snails with an abundance of food, thus accelerating their growth and causing them to attain an unusually large size, while the imbrications are correspondingly exaggerated.”
