About this map

Mining settlements and rugged canyon camps define this landscape during the peak years of Colorado's hard-rock extraction. The steep terrain of the Colorado National Forest is etched with the intricate infrastructure of the Colorado and Northwestern RR, which snakes through the foothills to serve remote outposts like Wallstreet, Crisman, and Salina. At higher elevations, the Golden Rule Mining Co Ditch underscores the hydraulic demands of industrial mining near Cannon Mt.

Beyond the established hub of Boulder, smaller communities such as Jamestown, Sunshine, and Springdale appear as vital nodes of commerce and residence. Waterways like Fourmile Creek and Left Hand Creek cut deep gulches, dictating the layout of early roads and rail lines. The concentration of place names along these drainages reflects the intense geological interest of the era, from Gold Hill Sta down to the mountain hamlets of Wheelmen and Orodell.
