Driggs, Idaho 1832 "In July of 1832, this basin filled up with camps of trappers, traders, and merchants that spread across seven square miles, from the south end of Driggs all the way to Tetonia. Rocky Mountain Fur Company and American Fur Company were the two largest company camps, but plenty of smaller independent camps were also represented, along with an estimated 108 Nez Perce lodges and 80 Flathead lodges. Jim Bridger was in attendance at the rendezvous.
