The Rocky Mountain Rendezvous was an annual rendezvous, held between 1825 to 1840 at various locations, organized by a fur trading company at which trappers and mountain men sold their furs and hides and replenished their supplies. The fur companies assembled teamster-driven mule trains which carried whiskey and supplies to a pre-announced location each spring-summer and set up a trading fair (the rendezvous). At the end of the rendezvous, the teamsters packed the furs out, either to normally the British Companies to Fort Vancouver in the Pacific Northwest for the British companies or to one of the northern Missouri River ports such as St. Joseph, Missouri, for American companies.
