About this map

Sourdough Spring and a series of high-desert water sources define this remote stretch of Malheur County, Oregon. The landscape is dominated by Sourdough Mountain and Grassy Mountain, with a network of basins and canyons supporting livestock and local wildlife. Strategic water management is evident through numerous improved sites like the Wildcat Canyon Reservoir, Table Reservoir, and Upper Kane Spring Reservoir.

Ephemeral drainage patterns are captured along Sand Hollow and Hoodoo Creek, while names like Whiskey Spring, Poison Spring, and Freezeout Lake suggest the difficult conditions faced by early travelers and ranchers. A solitary Jeep Trail provides the primary access through the Hoodoo Basin, connecting remote points like the Rye Field to the surrounding canyons. This 1967 field-checked survey preserves the ranching infrastructure and naming conventions of a quiet era in the Oregon high desert.
