In 1948 nearly twenty thousand acres along the Rocky Mountain Front west of Augusta was set aside as winter range for the Sun River elk herd. Increasing numbers of elk had been drifting out on ranch lands during the winter months and were presenting problems with established agricultural use. The Montana Fish and Game Department acquired two adjoining ranches in the foothills just east of Sawtooth Mountain, some land was donated and the US Bureau of Land Management also set aside land to form the Sun River Game Range. This land lay directly in the path of major migration trails for elk in the winter months and has provided valuable range for the Sun River elk herd.
