Bear Valley dominates this high-altitude landscape in central Oregon, where the winding Silvies River and its numerous tributaries create a complex wetland system. The northern reaches of the Malheur National Forest define the upland terrain, characterized by the Aldrich Mountains and the prominent volcanic spine of Starr Ridge. This survey illustrates a remote ranching and forest landscape, where infrastructure is limited to isolated forest roads like Scotty Creek Rd and a high-elevation Emergency Airstrip. The drainage patterns here, including Eddington Cr and Jack Cr, tell the story of a watershed feeding the Silvies, while local landmarks such as Long Glade and Windy Point provide orientation across the vast open valley and timbered slopes of the High Desert periphery.
