Harney Co Malheur Co forms the central north-south dividing line across this high-desert landscape in southeastern Oregon. The terrain is characterized by expansive, open reaches like The Flats and seasonal water management points essential for land use in this arid region, most notably the Lower Willow Cr Waterhole. In the southeast corner, the elevation rises toward Twin Buttes, providing a rare point of topographical relief. This 2023 survey serves as a contemporary record of these boundary lines and natural landmarks in a sparsely settled portion of the state where water sources and elevation markers are the primary indicators of human activity and property division.
