1894 Map of Rocky Bar

About this map

The high mountain settlements of Rocky Bar and Atlanta anchor this late nineteenth-century reconnaissance of the central Idaho wilderness. Located along the steep drainages of the South Fork and Middle Fork Boise River, these outposts were established during a period of intense mineral exploration and remote habitation. The map reveals a landscape dominated by the branching headwaters of the Boise River system, including the Yuba River and Little Queen River, where small camps like Graham and Junction Bar sat at the base of formidable peaks. To the southwest, the area around Trinity Mt. and Trinity Lake highlights the high-elevation terrain that challenged early surveyors. This sheet preserves the early jurisdictional boundaries of Boise, Elmore, and Alturas counties, showing the network of creeks and ridges that defined the mining districts of the 1890s.
