1956 Map of Cooke City

About this map

Cooke City and Silver Gate serve as the primary human outposts in this high-altitude landscape where the Shoshone National Forest, Custer National Forest, and Gallatin National Forest converge. The 1956 field checks record an active mining legacy south of Daisy Pass, noting the Irma Mines, Mohawk Mine, and Copper King Mine tucked into the steep drainages. This period captures the region before the modern era of wilderness management, evidenced by the Cooke Ranger Sta and the Big Park Guard Station. High-elevation landmarks such as Granite Peak and Grasshopper Glacier anchor a terrain defined by complex water systems, including the Stillwater River and Clarks Fork Yellowstone River. Large alpine lakes like Upper Aero Lake and Mystic Lake are documented alongside specialized features like Chimney Rock and Fossil Lake, providing a precise look at the mid-century geography of the Montana-Wyoming border.
