1972 Map of Crazy Peak

About this map

Gallatin National Forest dominates this 1970s topographic study, capturing a high-altitude wilderness defined by glacial features and alpine lakes. The map straddles the boundary between Park and Sweet Grass counties, where the headwaters of Sweet Grass Creek and Cottonwood Creek originate. This period of the 1970s shows the landscape before modern climate shifts significantly altered high-altitude ice, most notably at the Grasshopper Glacier.
