1893 Map of Helena

About this map

Helena and the copper-rich camps of Butte anchor this late-19th-century reconnaissance of the Continental Divide. The landscape is a complex network of mining districts and transit corridors, where the Northern Pacific Railroad and Montana Central Railroad navigate the steep grades of Mullan Pass and Elk Park Pass. Early mining centers such as Marysville, Blackfoot City, and Rimini appear alongside Last Chance Gulch, illustrating the era's rapid industrial expansion.
