About this map

The town of Alamosa serves as the focal point for this mid-1960s landscape, where the Rio Grande meanders through a complex network of agricultural irrigation and municipal infrastructure. The map details the urban core including the Courthouse, Cole Park, and Boyd Sch, while the city's growth is marked by the Alamosa Municipal Airport and Sewage Disposal Ponds to the east. Transportation history is visible in the active Denver and Rio Grande Western line and a parallel Old Railroad Grade further north.

Water management defines the surrounding San Luis Valley terrain, illustrated by an intricate system of man-made waterways like the Excelsior Ditch and Costilla Canal. To the southeast, the Alamosa National Wildlife Refuge borders the Alamosa River, and the topography rises toward Hansen Bluff. This survey captures the transition from town limits to the high-desert wetlands and gravel pits that supported the local economy.
