This map of North America focuses on discoveries in the Pacific Northwest and Alaska. New Mexico encompasses present-day Louisiana and Texas. Alaska is still a bit misshapen but Capt. Cook's discoveries are shown, and there is good detail of the Aleutian Islands and the coast of Asia. Northern Canada is marked Parts Unknown, and northern California is New Albion. The eastern seaboard states all extend to the Mississippi River. The map was published by Charles Cooke in a later edition of Thomas Bankes's A New Authentic System of Universal Geography...; across the top neatline is a mostly erased imprint reading, "Engraved for Bankes's New System of Geography."
