Anson Archipelago

The Anson Archipelago was a designation for a widely scattered group of purported islands in the Western North Pacific Ocean between Japan and Hawaii. The group included Wake Island and Marcus Island, as well as many phantom islandssuch as Los Jardines, Ganges Island, Rica de Oro, and Rica de Plata (the latter two sometimes referred to as Roca de Oro and Roca de Plata).

The Archipelago was named after George Anson, who seized Spanish navigational charts of these waters during his voyage around the world.
