This uncommon regional map is hand colored to delineate the oversized counties that the western states and territories had at this time period. It shows towns, mountains, rivers, railroads, etc. There is great detail throughout including unexplored regions and gold and copper areas. The map was issued in Williams' People's Pictorial Atlas. He bought the plates from Rogers and Johnston and updated them. The maps in Williams' atlas used longitudinal projection lines, which increase in width the further south one goes, to more accurately reflect the curvature of the earth and distance between degrees of longitude.
