1968 Map of Lake Mc Donald East

About this map

Sperry Chalets stands as a focal point of human presence in this high-altitude landscape within Glacier National Park. This 1968 field-checked survey documents a dramatic topography defined by the Sperry Glacier and a complex network of glacial basins and high-mountain passes. The map details the primitive infrastructure of the era, from the remote Patrol Cabin near Harrison Lake to the vital backcountry routes like the Gunsight Pass Trail. The drainage patterns are clearly visible as meltwater flows from features like Feather Woman Falls and Beaver Medicine Falls into the larger valleys. Between the eastern shore of Lake McDonald and the towering heights of Mt Brown, the map illustrates a landscape where travel was dictated by the natural breaks at Lincoln Pass and Gunsight Pass, providing a record of the park’s interior before more modern developments.
