By beginning where the standard works leave off and carrying the story up to its logical conclusion in 1865, this book fills a definite void in the history of the fur trade in the American West. Set in the upper Missouri country, which was bypassed by settlement until the 1860s, it focuses primarily upon the St. Louis firm of Pierre Chouteau, Jr., and Company, usually known as the American Fur Company....This is not the distorted and romanticized approach so typical of much of the literature on the earlier fur trade. Drama is inherent, but it is sound, well-conceived, carefully documented history.-American Historical Review
