1949 Map of Mt. Hayes A-4

USGS Topo · Published 1987

About this map

Isabel Pass serves as a critical corridor through the high country of the Amphitheater Mountains, where the modern infrastructure of the Trans-Alaska Pipeline follows the historic path of the Richardson Highway. This intersection of geography and industry is centered around Summit Lake and the Summit Lake Lodge, marking a key transit point for travelers and logistics in the Alaskan interior. To the south, the settlement of Paxson marks the junction where the highway meets the Denali Highway, leading toward the water-rich landscapes of the Tangle Lakes and Hungry Hollow. The map reveals a high-elevation environment defined by massive glacial lakes like Fielding Lake and the winding course of the Delta River, illustrating the sparse but vital human presence through remote campgrounds, landing strips, and mountain monuments.
