Interesting map of North America falsely placing Arizona and Idaho.
This map extends to the Arctic Circle in the north, showing Chukchi lands, the Boreal Ocean, Shannon Island in Northeast Greenland, and Central America in the south, displaying the Gulf of Panama. It stretches from the Pacific Ocean in the west to the Atlantic Ocean in the east, fully illustrating the continent's eastern and western coastlines. It encompasses parts of Russia, Canada, the United States, Mexico, Guatemala, Nicaragua, and the West Indies, as well as the islands north east of North America in a supplement. In the United States, Dufour inaccurately placed Arizona south of New Mexico and Idaho south of Montana instead of their actual locations to the west.
This map includes the names of numerous indigenous peoples and travel routes, such as the route from San Francisco to Cape Horn passing by Tahiti, the route from southern Europe to North America, and the route from the West Indies to Europe and vice versa. The author depicted the water bodies in the region, including rivers, lakes, streams, bays, gulfs, and seas, notably the flow of the Mississippi, the Gulf of Mexico, the Gulf of California, the Bering Sea and strait. Moreover, the author illustrated detailed representations of water and air currents, sometimes indicating the months of the year or seasons, notably the current in the Gulf of Mexico, the Sea of the West Indies, and the current on the California coast.
This map was published in the Atlas physique historique et politique de géographie moderne by Auguste-Henri Dufour and was engraved by Charles Dyonnet.
Auguste-Henri Dufour (1798-1865), often mistakenly referred to as Adolphe-Hippolyte Dufour due to his works signed A. H. Darfour. He was a skilled geographic engineer and a student of Lapie. His contributions to cartography were significant, with a prolific output of maps and atlases.
