Montezuma and the surrounding high-altitude mining districts are documented here in the early 1930s, showing a landscape defined by deep gulches and the high peaks of the Continental Divide. The map captures a transition era in the Colorado Rockies, where established industrial operations like the Waldorf Mine and the Hamill Mine sat alongside the evolving road networks of Loveland Pass and Argentine Pass. A power transmission line cuts through the mountains near Keystone, signaling the modernization of infrastructure across these steep grades. Early settlements such as Tiger, Swandyke, and Bakerville are shown in relation to the complex hydrology of the North Fork Snake River and Clear Creek. The survey also marks numerous United States Location Monuments, including USLM Decatur and USLM Adrian, which served as critical reference points for the dense network of mining claims that once blanketed this mineral-rich region.
