The legendary mountain men—the fur traders and trappers who penetrated the Rocky Mountains and explored the Far West in the first half on the nineteenth century—formed the vanguard of the American empire and became the heroes of American adventure. This volume brings to the general reader brief biographies of eighteen representative mountain men, selected from among the essay assembled by LeRoy R. Hafen in The Mountain Men and the Fur Trade of the Far West (ten volumes, 1965-72).
