2011 Map of Turnbull Peak

About this map

Turnbull Peak rises above a high desert landscape marked by industrial excavation and water management in Malheur County. This 2011 survey details a region defined by extensive mining pits such as Mud Puddle Pit, West Pit, and West Turnbull Pit, which are scattered throughout the valleys. The seasonal nature of the local hydrology is evident in features like the Duck Creek Lakebed and several engineered catchments, including South Turnbull Reservoir and Ryegrass Reservoir. To the south, the terrain climbs toward the Sheepshead Mountains, while the Ryegrass Ranch serves as a lone hub of activity along Iron Mountain Rd. The map illustrates how ranching and resource extraction have shaped this corner of Opal Valley and Barren Valley.
