About this map

Central City and the surrounding mining districts of Gilpin and Boulder Counties are captured here during a period of significant industrial activity. The landscape is a dense network of high-altitude settlements and infrastructure, including the Boulder County Mine and an extensive Aerial Tramway near Lawson. Beyond the major hubs like Nevadaville and Russell Gulch, the map reveals smaller work camps and remote post offices such as Bald Mountain P O.

Transport is defined by the steep grades of the Denver Northwestern and Pacific RR and the Colorado and Southern RR, which serviced the gold and silver operations. The Continental Divide forms a natural western boundary, separating the industrial valleys from the Arapaho National Forest. This survey provides a precise look at the early 20th-century mining economy, from the flumes and gulches to the high-mountain passes like Rollins Pass.
