About this map

Silver King Mine and the Columbia Mill anchor the northern reaches of this Idaho mining landscape, where early twentieth-century extraction defined the local economy and settlement patterns. The map details a network of high-altitude camps and operations, including Carrietown in the south, which served as a hub for the Silver Star Mine and the King of the West Mine. These settlements were deeply integrated with the rugged drainage systems of the South Fork Boise River and Big Smoky Creek.

The boundary line between Custer and Blaine counties traverses the peaks of the Sawtooth Mountains, separating the upper Salmon River waters from the Wood River valley. Geothermal features like Worswick Hot Springs and Hot Springs indicate the area's volcanic underpinnings, while the presence of the Rollins Placer and Rives Placer highlights the variety of mining techniques employed along these mountain waterways during the era of the U.S. Geological Survey fieldwork in the late 1890s.
