Vashon, Washington

Vashon (/ˈvæʃɒn/) is a census-designated place (CDP) in King County, Washington, United States. It covers an island alternately called Vashon Island or Vashon–Maury Island, the largest island in Puget Sound south of Admiralty Inlet. Before the construction of a tombolo built in 1913, Vashon Island and Maury Island were connected only during low tide; now they are considered a tied island.

The CDP's population was 11,055 at the 2020 census, up from 10,624 a decade ago. The CDP covers an area of 36.9 square miles (95.6 km²).

The island is connected to West Seattle and the Kitsap Peninsula to the north and Tacoma to the south via the Washington State Ferries system, as well as to Downtown Seattle via the King County Water Taxi. The island has resisted the construction of a fixed bridge to preserve its relative isolation and rural character. Vashon Island is also known for its annual strawberry festival, sheepdog trials, and agriculture.

Vashon Island sits in the midpoint of southern Puget Sound, between Seattle and Tacoma, Washington. In the nearby Pacific Ocean, roughly 170 miles (270 km) west of Vashon Island, lies the 700-mile (1,130 km) tectonic boundary known as the Cascadia Subduction Zone, and as such, Vashon Island is one of many areas at risk for earthquakes or related natural disasters. The Cascadia Subduction Zone last saw a major rupture in 1700, but the potential of the zone could cause one of the worst natural disasters in the history of North America.

Up until the late 18th cenutry, Vashon and Maury Islands were inhabited solely by American Indians, and there is evidence of human activity on Vashon Island dating back 10,000 to 12,000 years. Historical data from the era when the first Native Americans settled Vashon–Maury Island is limited. Some of the Native peoples known to have lived on Vashon Island were the Marpole culture from about 7,000 years ago, Coast Salish peoples about 1,000 years ago, and the Sqababsh (known in Chinook Wawa as the S'Homamish) starting about 500 years ago, the latter of which established 5 known major village sites. The Tulalip Tribe established villages along the shores of both islands. Fishing was abundant in the cold saltwater of the central Puget Sound basin, helping Native American tribes to thrive. Moreover, the many waterways and inlets provided easy travel by way of canoe.

The first non–Native American to explore and the first to chart this island was Captain George Vancouver, during his surveys of the Puget Sound area with the British Royal Navy. The island was named on May 28, 1792, by Vancouver after his friend James Vashon of the Royal Navy. Starting in 1824, different explorer and settler groups stayed on Vashon Island.

Maury Island, immediately to the southeast of Vashon, was named in 1841 by then Lt. Charles Wilkes in honor of William Lewis Maury, an officer in the United States Exploring Expedition. Maury was naturally separated from Vashon by a narrow passage, until local landowners decided to build an earth bridge, or isthmus, linking them together in 1916, thus creating the hamlet of Portage. Therefore, the two-piece isle was renamed Vashon-Maury Island. Between the two sections, it covers nearly 37 square miles (96 km²).

The first logging on the island began in 1852. By 1855–1856, the S'Homamish people were interned at Fox Island. European-Americans settled Vashon Island between 1865 and 1890. During that time the main economies on the island were fishing and logging.
