1957 Map of Cuprum

About this map

Cuprum and its surrounding mountain terrain are defined by a history of mining and remote settlement along the Snake River canyon. This 1957 field survey documents the high-elevation landscapes of the Seven Devils Mts, where numerous mines such as the Red Ledge Mine and South Peacock Mine operated. The map captures transition points where former mining camps like Helena and Landore had already become historical markers, while active livestock operations like Barrinaga Corrals and Lynes Ranch persist in the lower drainages. The complex topography features dramatic elevation changes from Eagle Bar at the river's edge up to Monument Peak, reflecting the area's difficult accessibility and dependence on pack trails and mountain roads. Water sources like Black Lake, Satan Lake, and the many gulches feeding into Granite Creek provided essential resources for both prospectors and ranchers in this part of the Wallowa National Forest.
