This classic, scholarly history of the fur trappers and traders of the early nineteenth century focuses on the devices that enabled the opening of the untracked American west. Sprinkled with interesting facts and old western lore, this guide to traps and tools is also a lively history. The era of the mountain man is distinct in American history, and Russell's exhaustive coverage on the guns, traps, knives, axes, and other iron tools of this era, along with meticulous appendices, is astonishing. The result of thirty-five years of painstaking research, this is the definitive guide to the tools of the mountain men.
