What is the X in X-mas?
any of the pioneers of the North American Rocky Mountain West who went to that region first as fur trappers. Attracted by the beaver in virgin streams, the trappers became the explorers of the Far West. The most experienced trappers were the French, who were joined by American and Spanish fur traders. In the early 19th century, St. Louis was an important base for them for trading groups and trading-company caravans. Mingling extensively with the Indians, the mountain men adopted many of their manners of life and their beliefs as well as their love of adornment. Summer rendezvous, especially at Green River (in present-day Wyoming), became an institution of the mountain men, combining trade with recreation. As permanent settlers arrived, many mountain men served as scouts and guides, but their way of life was gradually eliminated by advancing civilization.
