San Juan Archipelago

The San Juan Islands are an archipelago in the northwest corner of the contiguous United States between the U.S. mainland and Vancouver Island, British Columbia, Canada. The San Juan Islands are part of the U.S. state of Washington.

In the archipelago, four islands are accessible by passenger ferry operated by the Washington State Ferries system.

Archaeologists use the term "Gulf of Georgia Culture Area" to refer to the San Juan and Gulf Islands, the whole of which shows many archaeological commonalities. The San Juan Islands were part of the traditional area of various peoples of the Coast Salish ethnolinguistic group. Linguistically, Coast Salish groups in the area consist of the Nooksack, Northern Straits (which includes the Lummi, Klallam, Saanich, Samish and Songhees dialects). Exploration and settlement by Europeans brought smallpox to the area by the 1770s.

The explorations of 1791 were carried out in partnership with the Royal Navy ships under the command of George Vancouver, while American explorations were led by Charles Wilkes. Despite having colonized the area entirely, the British and Americans retained many of the Spanish names which survive today.

The name "San Juan" was given to the islands by the Spanish explorer Francisco de Eliza, who charted the islands in 1791, naming them Isla y Archiepelago de San Juan. The expedition sailed under the authority of the Viceroy of Mexico, Juan Vicente de Güemes Padilla Horcasitas y Aguayo, 2nd Count of Revillagigedo and Eliza named several places for him, including the San Juan Islands, Orcas Island (short for "Horcasitas") and Guemes Island. San Juan Island's first European discoverer was one of the officers under Eliza's command, Gonzalo López de Haro, for whom Haro Strait is named. The Spanish had found the islands a year earlier during the exploring voyage of Manuel Quimper on the Princesa Real, but it was not clear to them that they were islands.
