1957 Map of Trail Mountain

About this map

Arapaho National Forest defines the western landscape of this mid-century survey, where timber and ranching interests met the growing demand for water management. The map documents a rugged terrain marked by the Lumber Camp and established livestock operations like the Slash J Slash Ranch and Miller Hereford Ranch. At the heart of the area, the engineering of the Willow Creek Reservoir is captured shortly after its completion, showcasing the complex network of the Pump Canal and Blinte Highline Ditch designed to redirect alpine flows.
