This fascinating map is centered roughly on Santa Fe. It covers the area from the Arkansas River south to the 31st parallel and locates Albuquerque and Tucson. The parallels were being corrected from an incorrect position previously mapped, and this map illustrates both old and new parallels. The map presents topography, hydrology, Gen. Kearny's route, the route of the Santa Fe Expedition, the old Spanish military road, and more. It was one of the key maps in the Bartlett correspondence regarding the dispute over the survey of the Mexican border.
