“County Map of Dakota, Wyoming, Kansas, Nebraska and Colorado.” Philadelphia: S. Augustus Mitchell, Jr., 1870. 20 x 14 3/4. Lithograph. Original hand color. With old repairs at centerfold separation. Otherwise, very good condition.
Of particular interest is the depiction of the railroads, which are indicated sometimes following the early routes of explorers, also shown on the map. The Union Pacific Railroad, completed just the year before this map was published, is shown running through Nebraska to Cheyenne and then west, while the two railroads into Denver-one to Cheyenne to meet the Union Pacific and one directly east to Kansas City–both completed just the year this map was issued–are both shown. Also indicated was a proposed route for the just begun Northern Pacific through Dakota.
