1899 Map of Crandall

About this map

The Sunlight Mining Region serves as the economic centerpiece of this late 19th-century reconnaissance, capturing a high-altitude wilderness on the cusp of industrial interest. Located just east of the Yellowstone National Park boundary, the landscape is defined by the headwaters of the Clark Fork and the dramatic topography of Sunlight Basin. Geographer A.H. Thompson and topographer Frank Tweedy documented a region of extreme verticality, where prominent landmarks like Stinkingwater Peak and Pilot Peak guided early travelers and prospectors alike. The map illustrates the early boundaries of the Shoshone National Forest, preserving a record of the drainage patterns and glacial cirques such as Silvertip Basin and Hoodoo Basin before modern road networks penetrated these high ranges.
