About this map

Boulder River and its surrounding valleys dominate this turn-of-the-century landscape, serving as a hub for both industrial mining and burgeoning recreational sites. The town of Boulder stands as a central junction where the Great Northern R. R. meets several regional branches, including the Wickes Branch. Nearby, Boulder Hot Springs represents a destination for early Montana travelers, contrasting with the heavy industrial operations at the Amazon Mill and Mina Mine.

Hard-rock mining activity is pervasive throughout the district, with numerous claims such as the Hidden Treasure Mine, Free Coinage Mine, and Ruby Mine dotting the drainages. The Continental Divide forms a natural boundary to the west, where the Central Montana R. R. snakes through Elk Park toward Woodville. This era's infrastructure is further detailed by landmarks like the Butte Hospital and the Columbia Garden at the southern edge, illustrating the complex social and economic fabric of the region during its mineral boom.
