The Washington Islands National Wildlife Refuges were established by Theodore Roosevelt in 1907. They comprise 125-acre Flattery Rocks, 300-acre Quillayute Needles, and 60-acre Copalis, stretching off-shore from Cape Flattery all the way south to Copalis, Washington. More than 600 islands, rocks, and reefs comprise the refuges, and all but Destruction Island were designated as Wilderness Areas in 1970. The islands range from less than 1 acre to about 36 acres, and most drop abruptly into the sea. They provide nesting habitat for more than 70 percent of Washington's seabirds and support some of the largest seabird colonies in the continental United States. Some of the highlighted species include common murre, tufted puffin, Brandt cormorant, and rhinoceros auklet. Marine mammals such as the charismatic sea otter, harbor seal, Steller sea lion, California sea lion, and northern elephant seal regularly haul out onto the islands to rest, and they commonly and feed in waters surrounding the refuges. To prevent disturbance to extremely sensitive seabirds and marine mammals, Washington Islands Wilderness is closed to pulic entry year round and waters within 500 feet are designated as a voluntary closure to all watercraft.
