About this map

Blackbird Mountain and the surrounding high-altitude terrain of the Salmon National Forest define this 1980s landscape in Lemhi County. The map documents a significant intersection of protected lands, where the Frank Church-River of No Return Wilderness boundary meets the heavily dissected slopes of the Yellowjacket Mountains. Waterways like Yellowjacket Creek and Blackbird Creek carve deep drainages through the territory, highlighting the natural barriers that have historically shaped access to this part of the Salmon River mountains.

Prominent geographical markers such as Quartzite Mountain and Porphyry Ridge provide essential orientation for researchers studying the geomorphology of the region. The map also records the location of Remerclau Saddle and Red Rock Peak, illustrating the remote character of the backcountry before modern digital mapping. This survey serves as a precise record of the trail-and-drainage network that supported local forestry and mountain navigation during the late twentieth century.
