Bear Valley dominates this high-country landscape in Grant County, where the headwaters of the Silvies River meander through a wide mountain basin. This 1990 provisional survey records a rugged interior region of the Malheur National Forest, defined by the prominent Aldrich Mountains and Starr Ridge to the northeast. The map provides a clear look at the area's ranching heritage, showing established operations like Lowe Ranch, Holliday Ranch, and 96 Ranch situated near the valley floor. Water distribution is a central theme, with numerous diversion ditches and springs feeding into the drainage network of Scotty Creek and Damon Creek. The terrain transitions from the open glades of Wymer and Long Glade in the west toward the steep elevations of Windy Point, offering a detailed view of the forest boundary and the isolated outposts that characterize this part of eastern Oregon.
