Minnesota and Dacotah in 1860
The New General Atlas replaced Mitchell senior's equally popular New Universal Atlas (1846 - 59) and remained in print through later editions until 1893. The atlas was produced by lithography with color applied to each map by hand. Minnesota and Dacotahnull was apparently based on a combination of sources that included Joseph N. Nicollet's 1843 map of the Hydorgraphical Basin of the Upper Midwest River and Lt. Gouverneur K. Warren's 1858 Military Map of Nebraska and Dakota.
