1967 Map of Twin Springs

About this map

Twin Springs and a network of isolated water sources anchor this high-desert landscape in Malheur County during the late 1960s. The map captures the edge of Lake Owyhee as it reaches into the canyonlands, marked by a controlled inundation zone. To the west, the arid terrain of Sourdough Mtn and Sand Hollow is traversed by the Hammond Hill Trail and various jeep tracks, indicating a landscape used primarily for ranching and remote passage. Local hydrology is the defining characteristic of this survey, with numerous named points such as Whiskey Spring, Dead Horse Spring, and Wall Rock Spring serving as vital landmarks for those navigating the basins. The eastern edge reveals the significant topographical depression of Oxbow Basin, while the Dry Creek Buttes Reservoir provides evidence of water management efforts in the drainage south of the lake.
