About this map

The Laramie River and Cache la Poudre River headwaters define this high-altitude landscape along the Colorado and Wyoming border. Surveyed between 1914 and 1916, the map records a network of mountain settlements and early forest management infrastructure within the Roosevelt National Forest. Significant engineering is visible at the Laramie-Poudre Tunnel, a project designed to divert water between the two major drainage basins. Local life is anchored by small outposts like Glendevey, The Rustic, and Manhattan, the latter supported by a dedicated Manhattan Ranger Sta. Scattered ranching and educational sites, including the Black Mtn School and Bennett Ranch, appear alongside landmarks like Chambers Lake and the northern reaches of Rocky Mountain National Park. This survey captures the transition of the Larimer County backcountry from a remote ranching frontier into a managed national forest system during the early twentieth century.
