1954 Map of Allison

About this map

The Southern Ute Indian Reservation dominates the landscape of this Colorado and New Mexico borderlands survey, where high-desert mesas meet a complex network of irrigation and river valleys. The small settlement of Allison sits along an Old Railroad Grade, serving as a focal point for local history near the Cem and the locality of Graves. The southern portion of the sheet reveals the impact of water management in the arid West, showing the Navajo Reservoir and the San Juan River along with an extensive system of water works including the Pine River Canal and Darlington Ditch. Topographical landmarks like Piedra Peak and Haystack Mountain rise above the canyons of the Piedra River, illustrating the varied terrain of the Archuleta and La Plata county lines before they descend into the river basins.
