Pinedale, WY South Side City Limits Welcome to Pinedale Wyoming, home of the oldest Mountain Man Rendezvous Pageant held during the Green River Rendezvous every year in July. Originally, the Green River Rendezvous was an annual event where mountain men, trappers, travelers and Indians all gathered in a valley 'below the Green' River to barter, trade, sell, and swap skins, pelts, guns, jewelry and whatever else they needed. The very mention of the the word Wyoming evokes the essence of the American West. Wyoming is all that innumerable movies, novels and legends have tried to capture. This Western Spirit thrives to this day in the Cowboy State. The name Wyoming has its origins in an Algonquin word meaning \"large prairie place \".
