Butte anchors the northern edge of this landscape, its industrial character marked by the Silver Bow Siding Chemical Plant and the intricate rail network of the Chicago Milwaukee St Paul and Pacific, Northern Pacific, and Union Pacific lines. This survey captures a transitional moment for the region’s geography, where the urban outskirts of the mining city give way to the Deerlodge National Forest and the winding course of the Continental Divide.
