About this map

Big Mowich Mountain and the surrounding high country of the Ochoco National Forest dominate this high-altitude landscape. The terrain is defined by a dense network of springs and seasonal drainages that feed into major waterways like Silver Creek and the South Fork Beaver Creek. Geologic features such as Robertson Ridge and Little Mowich Mountain are carved by these numerous water sources, including the curiously named Sinking Spring and Whistle Spring.

A network of forest roads and county highways, including County Highway 69 and Donnelly Road, provides access to remote locations like Button Flat and Lehman Meadow. The boundary between Grant and Harney counties cuts across the northern peaks, marking a divide in this timber-rich region. This map illustrates the vital role of water management and forest access in the high desert hinterlands of eastern Oregon.
