This is an account by Henry Rowe Schoolcraft (1793-1864) of his discovery of the Mississippi River's source, Lake Itasca, in 1832. Schoolcraft was an Indian agent for the region, and he assembled an expeditionary party of thirty, including Ozawindib (an Ojibway guide and interpreter), an army officer, a surgeon, a geologist, and interpreter, and a missionary. They set out with instructions from Secretary of War Lewis Cass to effect a permanent peace among the region's Native Americans, persuade them to be vaccinated against smallpox, acquire demographic and scientific information, and establish definitively the origin of the Mississippi. Expedition Through the Upper Mississippi contains anecdotes and observations about the beliefs, customs, and history of the Chippewa [Ojibway] as well as the Sioux [Dakota], the Fox [Mesquakie], the Sauk, the Menominee, the Mandans, and various other Native American groups. The narrative proceeds chronologically along the route the expedition followed, with detailed descriptions of geographical features. This volume also includes a short account of a trip along the St. Croix and Burntwood (Brule) River, and has an appendix containing statistical and linguistic data, a list of shells collected by Schoolcraft in the West and Northwestern territories, official reports, a speech by six Chippewa chiefs about the war delivered at Michilimackinac in July 1833, and a discussion of the Upper Mississippi's lead mining country.

Scientist, explorer, historian, and Indian agent Henry Rowe Schoolcraft's name must be included in the pantheon of early nineteenth-century adventurers who were in the vanguard of American expansion into the heart of the continent. While some, individuals like William Clark, Meriwether Lewis, John C. Fremont, and Kit Carson did not stop until they reached the Pacific Ocean, others took it as their task to explore the cast, unknown interior; chief among this group was Henry Rowe Schoolcraft. Originally issued by Michigan State University Press in 1958, Schoolcraft's Expedition to Lake Itasca contains a semi-official report of his 1832 trip to the upper Mississippi region. His purposes for exploring the area, now part of Minnesota, were to quell a feud between warring Chippewa and Sioux factions and to locate the Mississippi headwaters. Although he did not stop the fighting, Schoolcraft did discover the river's true source and left us an unsurpassed account of life in the region in the 1830s. Anyone interested in the early white exploration of the upper Midwest should own a copy of this valuable resource.
