What stands out about Vashon’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
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.
The Vashon post office opened in 1883, the earliest record of the town by name (U.S. post office records).
