Folly Farm sits at the convergence of high desert transit routes in southeastern Oregon, marking a distinct point of human activity within a landscape of broad basins and volcanic uplands. This 2020 survey illustrates a region defined by its water-management features and drainage patterns, from Porcupine Reservoir and Lake Pit in the north to the sprawling Duck Creek Lakebed in Barren Valley. The settlement at Folly Farm is flanked by the Folly Farm Flat and the rising elevations of the Sheepshead Mountains to the southeast. Roads like Folly Farm Rd and Crowley Riverside Rd connect the area's few ranching and aviation landmarks, such as the Black Bull Spring Ranch Airport. Topographic features like Lambing Canyon, Baker Pass, and Opal Valley highlight the varied terrain used for livestock and remote homesteading on the border of Harney and Malheur counties.
