Bear Valley and the Aldrich Mountains define this high-altitude landscape in Grant County, where the headwaters of the Silvies River wind through open flats and timbered slopes. This 2024 survey captures a terrain dominated by the Malheur National Forest and a series of high-desert drainages. The hydrology of the area is particularly detailed, showing the convergence of Scotty Creek, Eddington Creek, and Damon Creek.
