1909 Map of Mount Jackson

About this map

Aspen serves as the hub of this early 20th-century landscape, a period when silver mining and mountain transit shaped the development of Pitkin County. The high-altitude terrain is defined by the Colorado Midland Railway following the Fryingpan River through the northern corridor, while the Denver and Rio Grande Railroad reaches into the heart of the mining districts. Small rail stops and mining camps like Sallan, Nast, and Ruedi appear alongside larger operations such as the Little Annie Mine and Montezuma Mine. Beyond the industrial activity, the map identifies local landmarks like the Taylor School and the remote settlement of Ashcroft, providing a record of the community's footprint before the later 20th-century shift toward recreation and tourism. The intricate topography reveals the challenging routes over Independence Pass and the steep elevation of the Williams Mountains.
