1954 Map of Allison

About this map

The Southern Ute Indian Reservation dominates this 1954 landscape, where the confluence of the Piedra River and the San Juan River has been transformed by the rising waters of the Navajo Reservoir. The map documents a critical era of transition, showing areas of controlled inundation in purple that reshape the historic river valleys. Near the settlement of Arboles, evidence of early infrastructure remains visible, including an Old Railroad Grade and the Pine River Canal. Further west, the town of Allison sits near Sambrito Creek, while the high country is marked by prominent landforms like Piedra Peak and Haystack Mountain. This survey is particularly useful for tracing submerged topography and identifying local landmarks such as the Navajo Landing Strip and a small Cem before the reservoir reached its full extent.
