The international boundary between Alaska and British Columbia carves through a landscape dominated by massive ice fields and the high peaks of the Tongass National Forest. Surveyed in the mid-1950s, this area shows the specialized infrastructure required for high-altitude resource extraction, including an Aerial Tramway and a Tractor Trail leading toward the Riverside Mine near the banks of the Salmon River.
