About this map

Virginia Valley defines the northern reaches of this high-desert landscape in Harney County, where the historic Virginia Valley School once served the local ranching community. The map reveals a land shaped by both volcanic geology and water management, featuring landmarks like Malheur Cave and the distinctive Hole in the Ground. Rising above the basins, Anderson Mountain and Riddle Mtn provide significant vertical relief, the latter topped by the Riddle Mtn Lookout.

Remote outposts and early settlement traces are scattered across the terrain, including Tommies Homestead and the Keuny Cabin (Ruins) near McBain Flat. A network of water resources such as South Fork Reservoir, Ten Cent Lake, and Reeds Basin Reservoir illustrates the importance of water storage for livestock in this arid region. The presence of a Landing Strip and the winding Juniper Grade trail indicate the infrastructure used to navigate and manage this expansive territory.
