Hundreds of trappers and traders and thousands of Indians gathered on the banks of the Green River for the rendezvous of 1833, 1835, 1836, 1837, 1839, and 1840, exchanging a year’s beaver harvest for supplies for the coming year. After long seasons of trapping, rendezvous offered a chance to reunite with friends and celebrate with contests, shooting, racing, drinking, laughter, and boasting, and these July gatherings could last a month, earning the name “trapper’s holiday” from Benjamin Bonneville. Great excitement greeted the arrival of the supply caravan after its 1200-mile journey from St. Louis to the Rocky Mountains, mainly with pack mules and two-wheel carts called charrettes carrying thousands of pounds of trade goods, and thousands of pounds of beaver pelts were then taken back to St. Louis. At the time these adventurers were known as mountaineers, now called mountain men, and rendezvous on the Green drew people of many nationalities, including American, British, Canadian, French, German, Mexican, Scottish, and Irish, among them Jim Bridger, William Sublette, Robert Campbell, Joseph Walker, Captain Bonneville, Thomas Fitzpatrick, Kit Carson, Nathaniel Wyeth, Lucien Fontenelle, Andrew Dripps, Joe Meek, Joshua Pilcher, Etienne Provost, and Moses Harris. Native tribes dominated the Rocky Mountains during the rendezvous era, and mountain men adopted parts of their material culture and often married into various tribes; Shoshone, Bannock, Flathead, Ute, and Nez Perce were friendly and always present in large numbers at the Green River Rendezvous, while members of the Delaware and Iroquois often joined American and British trapping brigades. Adventure seekers and missionaries also came: William Drummond Stewart first attended in 1833 and eventually came to six rendezvous, hiring Alfred Jacob Miller in 1837 to document his adventures as the only artist to attend and paint the mountain man rendezvous; beginning in 1834 with Jason Lee, missionaries accompanied the supply caravan, Marcus and Narcissa Whitman and Henry and Eliza Spalding attended the 1836 rendezvous, Narcissa and Eliza became the first white women to cross the Rocky Mountains, and Father Pierre-Jean De Smet offered the first Catholic Mass in what is now Wyoming during the 1840 rendezvous.
