The history of Native Americans in Yellowstone is extremely long, though it probably reached its height between 3,000 and 1,500 years ago. The numbers of people in the area started to go down after that, but significant populations remained all the same. As recently as the 19th century, in fact, there were up to ten different tribes residing within the vicinity of the lake. Photo credit: Mike Cline/Wikimedia Commons
