1949 Map of Mount Hayes A-4

About this map

The Amphitheater Mountains dominate this high-altitude landscape, recorded shortly after the mid-century as infrastructure began to weave through the passes. The Richardson Highway serves as the primary artery, cresting at Isabel Pass and passing the Summit Lake Lodge along the eastern shore of Summit Lake. This area represents a critical watershed junction, where the Delta River flows northward toward the Tanana, while the Gulkana River headwaters emerge near Summit Lake to flow south toward the Copper River.
