1954 Map of Sliderock Mountain

About this map

Iron Mountain Mine and the Silver King Mine anchor a landscape defined by mid-century extraction and wilderness management. Situated along the boundary of Sweet Grass and Stillwater Counties, this territory was meticulously mapped by the Tennessee Valley Authority for the Missouri River Basin development program. The map documents an intricate network of narrow gulches, such as Placer Gulch and Fire Gulch, which served as the primary conduits for early prospecting. The presence of Wepler Cabin and various jeep trails and pack trails indicates the remote nature of human habitation and travel during this era. High peaks like Sliderock Mountain and Ellis Mountain dominate the terrain, which transitions from the Gallatin National Forest to the Custer National Forest, illustrating the vast reach of federal forest reserves in south-central Montana.
