About this map

The city of Alamosa serves as the focal point for this mid-1960s study of the San Luis Valley, revealing an urban core defined by its Courthouse and the Boyd Sch. The landscape is intricately managed through an extensive network of irrigation and drainage infrastructure, including the Waverly Drain, Costilla Canal, and Seamans Ditch, which redirect water across the flat basin. This water management is vital for the region's agricultural character, evidenced by the numerous flowing wells scattered across the valley floor.

Transportation and conservation also shape the terrain, with the Denver and Rio Grande Western railroad passing through the city and an Old Railroad Grade visible to the north. To the southeast, the Alamosa National Wildlife Refuge borders the meandering Rio Grande, while the Alamosa River flows toward its junction near Adams Lake. The presence of the Alamosa Municipal Airport and Municipal Golf Course indicates the mid-century expansion of local infrastructure.
