The Garnet Range dominates this West-Central Montana landscape, a region defined by early 20th-century mining camps and narrow mountain valleys. Following surveys in 1915 and 1919, the map reveals a corridor of activity along the Clark Fork river, where the Northern Pacific and Chicago Milwaukee and St Paul railroads run parallel through the canyon. High in the mountains, mining outposts like Garnet and Coloma are shown alongside the distinctive Copper Cliff.
