Juan de Fuca Strait

The Strait of Juan de Fuca (officially named Juan de Fuca Strait in Canada) is a large body of water about 95 miles (153 km) long that is the Salish Sea's outlet to the Pacific Ocean. The international boundary between Canada and the United States runs down the center of the Strait.

It was named in 1787 by the maritime fur trader Charles William Barkley, captain of the Imperial Eagle, for Juan de Fuca, the Greek navigator who sailed in a Spanish expedition in 1592 to seek the fabled Strait of Anián. Barkley was the first non-indigenous person to find the strait, unless Juan de Fuca's story was true. The strait was explored in detail between 1789 and 1791 by Manuel Quimper, José María Narváez, Juan Carrasco, Gonzalo López de Haro, and Francisco de Eliza.

The USGS defines the Strait of Juan de Fuca as a channel. It extends east from the Pacific Ocean between Vancouver Island, British Columbia, and the Olympic Peninsula, Washington, to Haro Strait, San Juan Channel, Rosario Strait, and Puget Sound. The Pacific Ocean boundary is formed by a line between Cape Flattery and Tatoosh Island, Washington, and Carmanah Point (Vancouver Island), British Columbia. Its northern boundary follows the shoreline of Vancouver Island from Carmanah Point to Gonzales Point, then follows a continuous line east to Seabird Point (Discovery Island), British Columbia, Cattle Point (San Juan Island), Washington, Iceberg Point (Lopez Island), Point Colville (Lopez Island), and then to Rosario Head (Fidalgo Island). The eastern boundary runs south from Rosario Head across Deception Pass to Whidbey Island, then along the western coast of Whidbey Island to Point Partridge, then across Admiralty Inlet to Point Wilson (Quimper Peninsula). The northern coast of the Olympic Peninsula forms the southern boundary of the strait. In the eastern entrance to the Strait, the Race Rocks Archipelago is located in the high current zone halfway between Port Angeles, Washington, and Victoria, BC.
