This uncommon map was published in a state atlas by Walling & Gray. The map, centered on the Black Hills, shows the states and territories in great detail with all counties individually hand colored. Dakota is still a single large territory with just a few counties organized along the boundary with Minnesota. Wyoming shows only five counties and the northwest of Nebraska is completely unorganized. The newly created Yellowstone National Park is delineated with a simple block outline in northwestern Wyoming. Details throughout show forts, railroads, wagon roads, springs, watershed and topography in hachure. A beautiful double page stone engraved map.
