The Continental Divide winds through the heart of the Northern Rockies in this 1960 edition, defining a landscape of high summits and industrial centers. Mining and smelting activity anchor the southern reach near Butte and Anaconda, while the state capital of Helena sits at the foot of the Helena National Forest. The map shows a region heavily shaped by transportation, with the Northern Pacific and Milwaukee Road railways threading through narrow river canyons alongside the Clark Fork and Blackfoot River.
