History
Blakely Island was named by Charles Wilkes during the Wilkes Expedition of 1838-1842, in honor of Johnston Blakeley, a naval commander during the War of 1812.[1] Thatcher bay, on the island's west coast, was the site of seasonal Samish tribal villages and, during the territorial period, the mill town of Thatcher, Washington.[2] In 2014, toxic creosote pilings left over from earlier habitation were removed from the waters of Thatcher bay.[3]
