1966 Map of Alamosa East

About this map

The Rio Grande and its complex network of irrigation channels define this San Luis Valley landscape during the mid-1960s. The city of Alamosa serves as the regional hub, where the Denver and Rio Grande Western railroad corridors meet the urban grid containing the local Courthouse and Boyd Sch. The surrounding terrain is characterized by an intensive water-management system essential for high-altitude agriculture, featuring named works such as the Excelsior Ditch, Chicago Ditch, and Waverly Drain. To the east, the Alamosa National Wildlife Refuge preserves the riparian wetlands along the river's winding course toward Hansen Bluff. This survey also records important civic infrastructure of the era, from the Alamosa Municipal Airport to the Municipal Golf Course, alongside rural landmarks like Adams Lake and various gravel pits.
