1952 Map of Mt. Hayes A-4

About this map

Isabel Pass serves as a critical focal point in this 1952 Alaskan interior survey, marking the divide where the Richardson Highway traverses the high mountain terrain. The map documents the early infrastructure of this corridor, including the Richardson Mon and various roadside Cabins, alongside established stopping points like McCallum and Summit Lodge. This area represents a vital transportation link connecting the interior, with the highway shadowing Phelan Creek before crossing the summit toward the Gulkana River drainage.
