Helena stands as the primary hub in this late nineteenth-century landscape, positioned at the edge of the Continental Divide and surrounded by a dense network of mining camps and early rail lines. The topography reveals the intense industrial activity of the era, with the Helena and Red Mountain Railroad and the Northern Pacific Railroad snaking through steep mountain passes to reach concentrated resource centers like Wickes, Rimini, and Marysville.
