About this map

Boulder serves as the focal point of this late 19th-century study, situated at the confluence of the Boulder River and Muskrat Creek. The landscape is dominated by the hard-rock mining industry of the Northern Rockies, featuring an extensive network of claims like the Free Coinage Mine, Grey Eagle Mine, and the Amazon Mill. Heavy rail infrastructure from the Montana Central R.R. and Northern Pacific R.R. dictates the pattern of settlement, threading through steep passes to connect industrial hubs like Wickes and Corbin.

Beyond the industrial corridors, the survey details high-altitude landmarks such as Bull Mountain and the thermal waters of Boulder Hot Springs. These features reflect a diversifying regional economy where mineral extraction coexisted with early tourism and timber management within the Helena National Forest. The presence of small rail stops like Calvin Sta. and remote camps such as Winters Camp provides evidence of the transient and localized nature of late Victorian-era mountain life.
