- Sand Island Natural Area Preserve (dnr.wa.gov)
This small sandy accretion island protects nesting seabird colonies, historically including Caspian terns. Bald eagles, double-crested cormorants, brown pelicans, brants, ring-billed gulls, sandpipers, and many other birds use the site. The island supports sand dune vegetation, and provides a haul out site for seals.
