2011 Map of Devine Ridge South

About this map

Jameson Ranch and the Old Graham Homestead anchor this high-desert portion of Harney County, illustrating the enduring presence of ranching and early settlement in the Oregon interior. The landscape is defined by the prominent Devine Ridge and a series of deep drainages including Armstrong Canyon, Gradon Canyon, and Tudor Canyon. Water sources are critical in this arid environment, evidenced by named features like Widow Spring, Soldier Spring, and Petersen Spring which feed into intermittent systems like Soldier Creek. In the southern reaches, Sand Hill rises near the junction of Old Harney Rd and N Harney Rd, routes that trace the historical movement of cattle and commerce between remote homesteads. The Armstrong Canyon Reservoir serves as a vital point for managing the seasonal flow of Prater Creek in this part of the state.
