Excellent map of America, featuring an unusual northwest coast of America, which includes Martin d'Aguilar's strait which provides for a Northwest Passage via the Great Lakes. The rest of the NW coast is virtually due North, with notations regarding Russian explorations in 1743. California is a Peninsula, with annotations regarding Quivira or Teguaio. Evidence of the claims of the various British and French colonies throughout, especially along the Eastern Seaboard. Overall a very attractive map, with a compass rose.
