Mormon pioneer Seth Tanner improved this prehistoric Indian
footpath in the 1880s to reach his mining claims along the
Colorado River. At one time this route was part of the
Horsetheif Trail. Outlaws stole horses in Utah and drove them
down the Nankoweap Trail from the North Rim, across the
river, and up the Tanner Trail to the South Rim.
