1967 Map of Mitchell Butte

About this map

Mitchell Butte dominates this high-desert landscape in eastern Malheur County, where the 1960s irrigation infrastructure of the Owyhee Project is meticulously documented. The complex engineering required to move water through this arid terrain is visible through features like the North Canal, the Cow Hollow Siphon, and Tunnel No 4. Along the southern edge, the Owyhee River carves through the basin, flanked by landmarks such as Mitchell Butte Hot Spring and the Owyhee Ditch. A network of rural avenues including Ivanhoe Ave and Klamath Avenue grids the flatter eastern benches, transitioning into the more varied topography of Chalk Butte and Fletcher Gulch. The map also captures several landing strips and local landmarks like Rock Spring, reflecting the area's remote ranching and agricultural character.
