Rocky Mountain Rendezvous

The Rocky Mountain Rendezvous was an annual rendezvous, held between 1825 and 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).
