Hydrological engineering and agricultural infrastructure dominate this mid-1960s survey of Alamosa County. The landscape is defined by an extensive network of water management features, including the Central Lateral, South Lateral, and the Costilla Canal. Numerous labels for Flowing Wells and a series of exploratory points like Drill Hole 7522 and Drill Hole 7527 suggest significant subsurface investigation and water sourcing efforts during this period.
