2014 Map of Turnbull Peak

About this map

Turnbull Peak rises above a high-desert landscape defined by arid basins and seasonal water management in Malheur County. This 2014 survey details the hydrology of the Barren Valley and Opal Valley, where the Duck Creek Lakebed and reservoirs like Turnbull Peak Reservoir and South Turnbull Reservoir indicate the region's reliance on collected runoff. The southern margin of the sheet is anchored by the Sheepshead Mountains and the edge of the Saddle Butte Lava Field, illustrating the volcanic origins of the local terrain.
