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.
