1954 Map of Trinidad

About this map

San Luis Valley agriculture and the high-altitude peaks of the Sangre de Cristo Range define this mid-century look at Southern Colorado. The geography is dominated by a complex network of irrigation systems including the Union Ditch, Empire Canal, and Costilla Canal, which support a series of settlements from Alamosa to San Luis. In the northeast, the Great Sand Dunes National Monument sits at the foot of massive summits like Blanca Peak and Kit Carson Mountain.
