Important early map of Minnesota Territory, including all of Dakota, from the 1850 editon of Mitchell's Universal Atlas. The map is based largely on the works of Nicollet and Pope, and includes extensive notes on early exploration and topography throughout. An essential map for Minnesota and Dakota collectors. One of the earliest editions of the map, first issued in 1850, the year after Minnesota became a territory. Massive Pembina and Dacotah counties in the west, with many Indian Tribes, forts and toerh early exploration notes shown. Narrow upper margin, with a tiny bit of loss to the neat line in one spot, else a very nice example. Normally a $400 map.
