1911 Map of Mount Jackson

About this map

Aspen serves as the focal point of this 1911 survey, situated at the confluence of the Roaring Fork and Castle Creek. The landscape is defined by the high-altitude mining and ranching economy of the early twentieth century, with the Little Annie Mine and Montezuma Mine marking the extraction history of the surrounding peaks. Transportation is dominated by the competing paths of the Colorado Midland RR and the Denver and Rio Grande RR, which navigated the formidable terrain to reach mountain outposts. The map documents numerous small settlements and stops like Ashcroft, Thomasville, and Ruedi, many of which were tied to the railroads or timber and mining interests. To the east, Independence Pass provides a vital crossing through the Williams Mountains, while water features like Loch Ivanhoe and the Devils Punchbowl illustrate the complex hydrology of the Continental Divide.
