1955 Map of Mount Hayes C-3

About this map

Gerstle Glacier dominates the southern reaches of this high-latitude terrain, its ice fields marked by shifting crevasses that feed a network of glacial meltwater streams. The Gerstle River carves a broad valley through the center of the sheet, joined by high-elevation tributaries such as July Creek and Sheep Creek. This mid-century survey captures an unpopulated wilderness defined by severe topography and the movement of water and ice, with St Anthony Pass serving as a notable corridor through the high peaks. The drainage patterns revealed here, including the Little Gerstle River and Pegmatite Creek, illustrate the complex hydrology of the Alaska Range before modern infrastructure reached this remote interior. The absence of roads or permanent settlements emphasizes the character of the land as it remained in the mid-1950s, a landscape shaped entirely by geological forces.
