1958 Map of Butte

About this map

The Continental Divide zigzags across this landscape, separating the headwaters of the Missouri River from the Clark Fork drainage. Mining and industrial activity are central to this mid-century view, anchored by the heavy concentrations of rail and resource extraction around Butte and Anaconda. Transport corridors follow the river valleys, with the Northern Pacific and the Chicago Milwaukee St Paul and Pacific railroads threading through the mountains alongside U.S. 10.
