Helena serves as the focal point for this late nineteenth-century landscape, where the convergence of the Montana Central Railroad and the Northern Pacific Railroad illustrates a rapidly expanding industrial network. The terrain is deeply marked by mining and transit, with numerous settlements like Marysville and Wickes emerging along the mineral-rich gulches and mountain passes. To the west, Deer Lodge acts as another significant hub, connected to the territorial capital by lines that navigate the formidable barriers of the Continental Divide at Mullan Pass and Priests Pass.
