1949 Map of Mt. Hayes A-1

USGS Topo · Published 1987

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.
