About this map

Illinois Peak anchors this high-altitude landscape along the Idaho-Montana border, where the headwaters of the Saint Joe River emerge from Saint Joe Lake. The terrain is deeply incised by numerous gulches and canyons, reflecting a long history of mineral extraction. Mining claims and operations are concentrated throughout the central drainages, including the Silver Snowstorm Mine near Freezeout Pass and the American Gold Mine along Cedar Creek.

Lesser-known sites like La Casse Camp and the Gildersleeve Mine point to the human activity required to work these remote slopes. The map also traces the drainage patterns of Rabbit Creek and Lost Creek, where Lost Creek Falls provides a rare named hydraulic feature. For those studying the industrial history of Shoshone County, the density of named prospects like the Cajun Queen Number 1 Mine and Silver King Mine suggests the intense late-20th-century interest in the region's mineral wealth.
