Mountain man

A mountain man is an explorer who lives in the wilderness and makes his living from hunting, fishing and trapping. Mountain men were most common in the North American Rocky Mountains from about 1810 through to the 1880s (with a peak population in the early 1840s). They were instrumental in opening up the various emigrant trails (widened into wagon roads) allowing Americans in the east to settle the new territories of the far west by organized wagon trains traveling over roads explored and in many cases, physically improved by the mountain men and the big fur companies, originally to serve the mule train-based inland fur trade.

Mountain men arose in a geographic and economic expansion that was driven by the lucrative earnings available in the North American fur trade, in the wake of the various 1806–1807 published accounts of the Lewis and Clark Expedition findings about the Rockies and the Oregon Country. They flourished for more than three decades, but their ability to make a good living through fur trapping had largely ended by the late 1840s—thanks to the rise of the silk trade, the collapse of the North American beaver-based fur trade since the 1830s, treaties signed in 1846 and 1848, and an upsurge in migration to officially settled western coastal territories in the United States.

Many of the mountain men settled into jobs as Army scouts, wagon train guides or settled throughout the lands which they had helped open up. Others, like William Sublette, opened fort-trading posts along the Oregon Trail to serve the remnant fur trade and the settlers heading west.

Mountain men were most common in the North American Rocky Mountains from about 1810 through to the 1880s. About 3,000 of them ranged the mountains between 1820 and 1840, the peak beaver-harvesting period. John Colter's solo exploration of 1807-1808 made him one of the first Mountain men. While there were many free trappers, most mountain men were employed by major fur companies. The life of a company man was almost militarized. The men had mess groups, hunted and trapped in brigades, and always reported to the head of the trapping party. This man was called a "boosway", a bastardization of the French term bourgeois. He was the leader of the brigade and the head trader.

Donald Mackenzie, representing the North West Company, held a rendezvous in the Boise River Valley in 1819. The rendezvous system was later implemented by William Henry Ashley of the Rocky Mountain Fur Company, whose company representatives would haul supplies to specific mountain locations in the spring, engage in trading with trappers, and bring pelts back to communities on the Missouri and Mississippi rivers, like St. Louis, in the fall. Ashley sold his business to the outfit of Smith, Jackson, and Sublette. He continued to earn revenue by selling that firm their supplies. This system of rendezvous with trappers continued when other firms, particularly the American Fur Company owned by John Jacob Astor, entered the field.

The annual rendezvous was often held at Horse Creek on the Green River, now called the Upper Green River Rendezvous Site, near present-day Pinedale, Wyoming. Another popular site in the same general area was Pierre's Hole. By the mid-1830s, it attracted 450 to 500 men annually: essentially all the American trappers and traders working in the Rockies as well as numerous Native Americans.

After achieving an American monopoly by 1830, Astor got out of the fur business before its decline. In the late 1830s, the Canadian-based Hudson's Bay Company (HBC) instituted several policies to undercut the American fur trade. During the same years, fashion in Europe shifted away from the formerly popular beaver hats; at the same time, the animal had become over-hunted. The HBC's annual Snake River Expedition was transformed into a trading enterprise. Beginning in 1834, it visited the American rendezvous to buy furs at low prices. The HBC was able to offer manufactured trade goods at prices far below that with which American fur companies could compete. The last rendezvous was held in 1840, when the HBC, along with a decline in demand for and supply of beaver, had effectively put all American fur traders out of business.

By 1841, the American Fur Company and the Rocky Mountain Fur Company were in ruins. By 1846, only some 50 American trappers still worked in the Snake River country, compared to 500 to 600 in 1826. Soon after the strategic victory by the HBC, the Snake River route was used by emigrants as the Oregon Trail, which brought a new form of competition. Former trappers earned money as guides or hunters for the emigrant parties.
