Open Valley dominates the central landscape of this Harney County quadrangle, where a series of ephemeral water sources supported the high desert cattle-ranching culture of southeastern Oregon. The 2014 survey documents a network of interior basins and depressions, including the named Flybee Lake, Flynn Lake, and Deep Canyon Lake. These seasonal features are joined by man-made or improved catchments like Open Valley Waterhole Number Three, illustrating the critical importance of water management in this arid region. The terrain is marked by distinctive geological formations such as Devils Canyon and the curiously named Hole in Rocks, while Smoky Hollow and Little Valley provide further definition to the local topography. This map serves as a detailed record of the Public Land Survey System boundaries, tracing the intersections of Townships 28, 29, and 30 South across Ranges 27 and 28 East.
