This extensive volume on the history of the Minnesota Valley includes sections by Edward Neill on the early explorers of Minnesota (Nicollet, Menard, Marquette, and Perrot, among others); the founding of the state; and the early history of the valley, including explorations of the Minnesota River, interactions among explorers, traders and local Indians, and steamboat navigation.
