The Alaska Central Railroad Tunnel Number 1 sits at the base of a high mountain corridor within the Chugach National Forest, marking a critical passage through the Kenai Peninsula. This 2018 survey detail shows a landscape dominated by massive ice fields and the deep carving of the Placer River Valley. The Placer River flows northward from the meltwaters of the Spencer Glacier, winding through the valley floor toward the boundary between the Kenai Peninsula Borough and the Anchorage Municipality. Hikers and researchers can trace the routes of the Spencer Glacier Trail and the Spencer Bench Trail as they navigate the slopes above the terminal lake. The map also records the positions of the Skookum Glacier, Deadman Glacier, and Bartlett Glacier, providing a clear record of the area's glacial extent and hydrologic network including Skookum Cr.
