About this map

The Southern Ute Indian Reservation dominates this mid-century landscape where the Piedra River and San Juan River converge near the Colorado and New Mexico border. The settlement of Allison serves as a local hub, situated near the tracks of the Denver and Rio Grande Western railroad. To the east, the village of Arboles sits at the junction of significant river canyons and rail lines, illustrating the importance of these natural corridors for western transit and trade.

Evidence of early agricultural engineering is visible through the Pine River Canal and Darlington Ditch, which redirect water across the arid terrain below Haystack Mountain. The map records several localized landmarks such as Graves and a small Cem, alongside rugged peaks like Piedra Peak. The intersection of multiple county and state boundaries highlights the complex jurisdictional history of this San Juan Basin region during the 1950s.
