A beautifully engraved and detailed map showing the United States possessions prior to the Mexican-American War. The region between the Mississippi River and Continental Divide is filled with Indian Districts and an ambiguous Oregon Territory extends north into Canada. The Republic of Texas is shown in an unusual small configuration with New Mexico and Indians lands occupying the panhandle. The Great Basin includes the S. Buenaventura R. running a supposed course to the San Francisco Bay and Nouvelle California is located along the coast. There is excellent detail throughout including Indian names, watersheds, railroads, forts, roads, and more. Surrounded by a decorative keyboard-style border.
