The Bitterroot River valley serves as the primary corridor for human activity on this 1980 survey, anchored by the seat at Hamilton. This narrow agricultural and residential strip stands in sharp contrast to the immense protected lands that flank it. To the west, the Selway Bitterroot Wilderness and Nez Perce National Forest cover the high country of the Bitterroot Range, while the Clearwater National Forest spans the northern reaches into Idaho.
