Fortress Island is one of the San Juan Islands in San Juan County, Washington, USA. Located in Lopez Sound, the uninhabited, rocky island has a land area of 3.21 acres (1.30 hectares) and is almost completely devoid of vegetation.[1] It is part of the Turtleback complex, a series of intrusive rocks in Lopez Sound formed out of crystallized molten magma that also includes Bird Rock, Low Island, and others.[2]
Fortress Island is part of the San Juan Islands National Wildlife Refuge and is managed by the U.S. Fish and Wildlife Service.[3] As with almost all of the islands in the refuge, human access is prohibited and boats may not approach to within 200 yards (180 m).[4]
