1954 Map of Allison

About this map

The Southern Ute Indian Reservation dominates this mid-century landscape where the Piedra River and San Juan River meet near the Colorado-New Mexico border. The settlement of Arboles sits at this major river junction, serving as a hub for the rail-and-water economy of the era. The Denver and Rio Grande Western railroad tracks trace a course through the valley, connecting the small community of Allison to the broader regional network. To the west, the irrigation infrastructure of the Pine River Canal and Darlington Ditch reveals the agricultural development of the Archuleta County terrain. The survey captures a moment before modern reservoirs altered these river valleys, documenting local landmarks like Haystack Mountain and the small settlement of Graves alongside family-named features and several Cem sites that provide valuable data for genealogical research.
