About this map

Jefferson City and its surrounding mining districts define this mid-century view of the mountainous Divide region between the Helena National Forest and Deerlodge National Forest. The landscape is densely packed with lode mining history, featuring concentrated workings such as the Bluebird Mine, Hattie Ferguson Mine, and the Washington Mines near Wickes. The industrial infrastructure of the era is evident in the Great Northern and Northern Pacific railroads that navigate the steep grades of the Occidental Plateau and Gregory Mountain.

Water management for these operations is marked by the Aqueduct leading from Chessman Reservoir and the network of Sloan Ditch and Sloan Flume near Amazon. Beyond the primary settlements, smaller outposts like Corbin, Comet, and the Sloan Ranch are clearly identified, while high-altitude landmarks like the Telephone Cabin and various beacons illustrate the remote communication and navigation needs of the 1950s Montana interior.
