Rocky Mountain Rendezvous (in trapper jargon) was an annual gathering (1825–1840) at various locations held by a fur trading company at which trappers and mountain men sold their furs and hides and replenished their supplies. The large fur companies put together teamster driven mule trains which packed in whiskey and supplies into a pre-announced location each spring-summer and set up a trading fair—the rendezvous—and at the season's end, packed furs out, normally the British Companies to Fort Vancouver in the Pacific Northwest, and to one of the northern Missouri River ports such as St. Joseph, Missouri, if an American overland fur trading company.
