History & geography

History

For thousands of years, Hat Island (known as in the Lushootseed language) was the site of a village of the Snohomish people. Their territory extended over the Snohomish River, as well as parts of Camano and Whidbey islands. The village was located on the north side of the island on a spit, near a spring. There were several longhouses. Hat Island was first mentioned in the historical record by naturalist Archibald Menzies of the Vancouver Expedition in 1792. In the 1820s, a large landslide at Camano Head created a tidal wave which crashed into Hat Island. The wave wiped out the village, save for a few survivors. From that point on, the island was only used by the Snohomish as a temporary camping ground when clamming, never as a permanent living site. People who returned occasionally found human remains or parts of the destroyed village. The island was named in English by Charles Wilkes in 1841; although other sources say it was for John B. Gedney or Jonathon Haight Gedney, Wilkes's memoirs say he named it for Lt Thomas R. Gedney. The name Hat is for the shape of a beach and treeless ledge, first used in 1870. Since 1980 the island would be called Gedney Island (Hat).
