1967 Map of Cairo

About this map

Malheur Butte dominates the northern horizon of this eastern Oregon landscape, standing as a prominent landmark near the intersection of the Malheur Union Pacific Canal and the Union Pacific railroad. The 1960s irrigation network is strikingly complex, featuring the Sheep Creek Siphon, Owyhee Ditch, and the Malheur Siphon Drive, illustrating the heavy engineering required to support agriculture across Big Sage Flats. Small rural hubs like Cairo Junction and Mallett serve the surrounding farmsteads, anchored by local institutions such as the Cairo Sch, Malheur Butte Ch, and a Grange Hall. Further south, the map details the residential and civic fringes of Nyssa, including the Nyssa Cem and the local High Sch, providing a clear record of the area's mid-century development and water management infrastructure.
