context_page_description: The American frontier includes the geography, history, folklore, and cultural expression of life in the forward wave of American expansion that began with English colonial settlements in the early 17th century and ended with the admission of the last remaining western territories as states in 1912. This era of massive migration and settlement was particularly encouraged by President Thomas Jefferson following the Louisiana Purchase, giving rise to the expansionist philosophy known as "Manifest Destiny" and the frontierist "Frontier Thesis".
  A frontier is a zone of contact at the edge of a line of settlement. Leading theorist Frederick Jackson Turner went deeper, arguing that the frontier was the defining process of American civilization: "The frontier," he asserted, "promoted the formation of a composite nationality for the American people." He theorized it was a process of development: "This perennial rebirth, this fluidity of American life, this expansion westward...furnish[es] the forces dominating American character."
context_section_description: As the frontier moved west, trappers and hunters moved ahead of settlers, searching out new supplies of beaver and other skins for shipment to Europe. The hunters were the first Europeans in much of the Old West and they formed the first working relationships with the Native Americans in the West. They added extensive knowledge of the Northwest terrain, including the important South Pass through the central Rocky Mountains. Discovered about 1812, it later became a major route for settlers to Oregon and Washington. By 1820, however, a new "brigade-rendezvous" system sent company men in "brigades" cross-country on long expeditions, bypassing many tribes. It also encouraged "free trappers" to explore new regions on their own. At the end of the gathering season, the trappers would "rendezvous" and turn in their goods for pay at river ports along the Green River, Upper Missouri, and the Upper Mississippi. St. Louis was the largest of the rendezvous towns. By 1830, however, fashions changed and beaver hats were replaced by silk hats, ending the demand for expensive American furs. Thus ended the era of the mountain men, trappers, and scouts such as Jedediah Smith, Hugh Glass, Davy Crockett, Jack Omohundro, and others. The trade-in beaver fur virtually ceased by 1845.
