Rocky Mountain Fur Trade

From the 1820s, fur companies sent organised trapping parties from the Missouri River into the Rocky Mountains in search of beaver pelts. Trappers worked through dangerous winters, river corridors and contested territories, depending upon Indigenous knowledge and trade even as commercial expansion increased conflict and ecological pressure.

The rendezvous system allowed trappers, merchants and Indigenous traders to exchange pelts, equipment and supplies without returning annually to eastern settlements. Figures such as Hugh Glass and Jim Bridger became part of the mythology of the mountain-man era, although their survival depended on company networks and cross-cultural relationships.

Declining beaver demand and depleted populations weakened the trade by the 1840s, but its routes and knowledge assisted later migration and state expansion.
