2023 Map of Square Mountain

About this map

Catlow Valley dominates this high-desert landscape in Harney County, illustrating the remote ranching and grazing infrastructure common to southeastern Oregon. Water management is a primary focus of this topographic study, with features such as Stockwater Ditch, The Trough, and the Rock Knoll Reservoir dotting the arid terrain. The landscape transitions from the flat expanse of Raz Lewis Flat and the Basque Hills in the southwest to the dramatic elevation of Catlow Rim and Square Mtn in the east. Local history is subtly recorded in family-named landmarks like Lee Morris Spring and McDade Cache. Access through this isolated region is defined by the CCC RD, a legacy of early 20th-century public works, and the main corridor of Catlow Valley Rd, which skirts the base of the eastern highlands.
