1964 Map of Sunbeam

USGS Topo · Published 1966

About this map

Bonanza and Sunbeam serve as the primary human touchpoints in this rugged section of the Challis National Forest during the mid-1960s. The landscape is defined by the steep drainage of the Yankee Fork as it flows south toward its confluence with the Salmon River. This area is a patchwork of early Idaho mining and forest management history, evidenced by the Lucky Boy Mine, scattered Mines, and expansive Tailings near the Bonanza Guard Sta. A small Cem near Bonanza suggests the long-standing community roots established during the region's mineral booms. Recreation and conservation are prominent features of the era, with numerous campgrounds such as Dutchman Flat Campground and Upper O'Brien Campground lining the river corridors. The presence of Indian Riffles and Sunbeam Hot Springs underscores the natural geothermal and hydrologic character that has drawn visitors to this part of Custer County for decades.
