1906 Map of Coeur D'Alene District

About this map

Mining operations dominate the landscape of the Shoshone County silver valley at the start of the 20th century. Major industrial centers like Wallace, Kellogg, and Mullan serve as hubs for the surrounding mountains, which are densely packed with underground workings. The northern part of the district around Murray and Delta shows the earlier gold-focused history of the region, while the canyon between Gem and Burke is a tight corridor of heavy industry, including the Hecla Mine and Standard-Mammoth Mine. Transport is defined by the competing interests of the Oregon Railroad & Navigation Co. and the Northern Pacific Railway, which follow the river forks to reach lucrative properties like the Bunker Hill and Sullivan Mines. Engineering feats of the era are evident in the Kellogg Tunnel and the Daisy Aerial Tramway, marking a period of intense extraction and technological growth.
