About this map

The Richardson Highway and the Alaska Pipeline parallel each other through this corridor of the Chugach Mountains, tracing a vital transportation and energy artery. The settlement of Ptarmigan sits along this route, flanked by the steep relief of Ptarmigan Drop and the waters of the Tsina River. This map shows a landscape defined by dramatic elevation changes, where drainage systems like Ptarmigan Creek, Cascade Creek, and Small Creek flow from the surrounding peaks toward the river valley. The presence of the Thompson Pass Airport highlights the area's role as a high-altitude transit point, providing critical access to this remote interior region. The boundary between the Copper River Census Area and the Chugach Census Area crosses the northern portion of the sheet, marking a transition in regional administration.
