Terrific early map of North America, prior to Lewis & Clark. The mythical River of the West extends from the Straits of Juan de Fuca (Pugent Sound) to the headwaters of the Mississippi. Carver's Oregan River, the first appearance of the name Oregon on a map, is present. The inaccurate NW Coast of America reflects the post-Cook, pre-Vancouver information provided by the British. Quivera and Tegauyo still appear in the West, as does New Albion, rather than Upper California. Sir Francis Drake's Harbor is shown, along with San Pedro and San Diego Bays and Santa Barbara. Dixon's entrance is noted above Queen Charlotte. In the midwest, Fort Detroit, Ft. Joseph, Ft. Miami and Ft. Pitt appear, along with Iowa Town. Texas and Cenis are both named. Many other early place names. Alaska is marvelously misconfigured. This is one of the earliest maps of North America to appear in an American published atlas.
