About this map

Twelvemile Ridge dominates this high-desert portion of Malheur County, providing a high divide between the seasonal drainages of the Great Basin. The landscape is defined by the sharp elevations of Three Man Butte and the long incline of Twelvemile Hill Grade. A network of unpaved ranch and range roads provides the only access through this remote territory, indicating the area's continued use for livestock grazing and land management.
