This site includes Port Angeles Harbor, Ediz Hook, and shallow marine waters immediately north and west of Ediz Hook. The eastern boundary is a line from the mouth of Lee???s Creek, running northwestward to a point 450 meters east of the tip of Ediz hook, where it intersects the 200-foot depth contour. The northern boundary follows the 200-foot depth contour until it intersects a line running due north from the point where the hook joins the mainland. This north-south line forms the western boundary. Port Angeles Harbor is the deepest harbor on the U.S. west coast, with depths up to 50 meters. It is protected from the open marine waters by Ediz Hook, a 5 km-long spit comprising about 80 hectares of sand/gravel beach and rocky breakwater. The port is highly industrialized and modified by human influences. It contains more than 100 pilings, and rafts of logs waiting export or use by nearby mills. The site contains large shipping facilities, a marina, and commercial net pens.

Ornithological Summary

Despite the intense human use, the sheltered waters behind Ediz Hook are an essential roosting and foraging area for wintering and migrating waterfowl and other aquatic birds, especially during periods of severe weather. Floating logs and pilings are preferred roosting habitat for herons, gulls, shorebirds, and Bald Eagles. Gull numbers often reach into the thousands. The site regularly supports more than 100 wintering Great Blue Herons. The Harbor supports the largest wintering concentrations of Barrow?s and Common Goldeneyes and Harlequin Ducks on the northern Olympic Peninsula. Waters immediately offshore outside the hook support significant feeding concentrations of alcids, gulls, and sea ducks throughout the year. The harbor supports large post-breeding dispersal flocks of Heermann?s Gulls and migratory populations of Thayer?s Gulls.

Data in the nomination document use of the site by Heermann's Gulls back to 1997. Observations from 1997 - 2005 indicate a low count of 100 (10/98) to a high of 3,000 (7/03).

Conservation Issues

Threats to this site are largely undocumented and poorly understood. Further research should be conducted in this arena.


Habitat is mostly deep marine waters protected from wave action by Ediz hook. Bottom is primarily gravel and coarse sand around edges, with fine sediments underlying deeper waters. Normal tidal range is 2.2 meters, extreme range 3.3 meters. Wave action impacts mostly the outer shore of Ediz hook, which is armored by a boulder revetment. Four small steams enter the harbor, one of which is undergoing estuarine restoration.

Land Use

Port Angeles is an active sea port with commercial shipping, naval activities, ferry service, and recreational boating.
