About this map

Isabel Pass serves as a critical corridor through the eastern Alaska Range, where the Richardson Highway and the Trans-Alaska Pipeline parallel one another through the high-altitude terrain. The landscape is defined by massive water bodies and mountain structures, including the Amphitheater Mountains and the sprawling Summit Lake. This 1949 survey, with revisions through the mid-1970s, documents the intersection of essential infrastructure and remote wilderness.

Local landmarks such as the Summit Lake Lodge and Richardson Monument mark the presence of travelers and early explorers in this demanding environment. The map details the headwaters of the Gulkana River and the complex drainage of the Tangle Lakes system, including Lower Tangle Lake and Round Tangle Lake. The southern portion of the quadrangle shows the beginning of the Denali Highway near Paxson Mountain, highlighting the area's role as a junction for interior Alaskan travel and transport.
