2017 Map of Rooster Comb

About this map

Lake Owyhee dominates this landscape in Malheur County, winding through the canyon system of eastern Oregon. The serpentine waterway is bounded by the sharp rise of Rooster Comb and the high elevations of Mahogany Mtn, which define the topography east of the reservoir. A network of drainages and springs, such as Shadscale Spring and Gin Spring, indicate the critical role of water management in this arid environment, further evidenced by the Gin Basin Reservoir located at Gin Basin. Settlement history is reflected in names like Schoolhouse Gulch and Dago Gulch, while the isolated Doe Island sits within the flooded canyon. The geography is characterized by dramatic shifts in elevation, from the flat expanse of Shadscale Flat to the plateaus of N Table Mtn and S Table Mtn.
