1891 Map of Leadville

About this map

The high-altitude mining district surrounding Leadville dominates this late-nineteenth-century reconnaissance survey, capturing a landscape transformed by the silver boom. The network of competing railroads, including the Denver and Rio Grande Railroad, the Union Pacific Railroad, and the Colorado Midland Railway, reveals the intense industrial pressure of the era. These lines climb through steep passes like Fremont Pass and Tennessee Pass to reach specialized settlements and mineral hubs. To the east, the map details the early development of Breckenridge and the small mining camps of Kokomo and Robinson along the East Fork Eagle River. Prominent peaks like Mt of the Holy Cross and Mt Elbert define the horizon, while smaller mining sites such as Oro and Dudley illustrate the dense settlement pattern of the central Rockies during their primary extractive age.
