This very scarce map was drawn from Lieut. Allen's observations taken during the important expedition that established Lake Itasca as the source of the Mississippi. It shows an interconnecting chain of lakes and waterways ending at Lake Itasca with an adjacent notation stating the lake is "the source of the Mississippi river _ length from the gulf of Mexico 3,160 miles elevation 1500 ft - reached 13th July 1832." The map locates trading posts just north of Lake Winnipeg and on Leech Lake and an Indian village on Leech Lake, otherwise there are no settlements noted. Schoolcraft published in 1821 a larger map in A Narrative Journal of Travels Through the Northwestern Regions...to the Sources of the Mississippi River. This Royal Geographical Society map is taken from the smaller one published by Schoolcraft in his History of the Indian Tribes.
