8In 1886 Walter McClintock went to northwestern Montana as a member of a U.S. Forest Service expedition. He was adopted as a son by Chief Mad Dog, the high priest of the Sun Dance, and spent the next four years living on the Blackfoot Reservation. The Old North Trail, originally published in 1910, is a record of his experiences among the Blackfeet.
