Aldrich Mountains peaks define this portion of the Malheur National Forest, where a network of trails and springs supported early resource extraction and land management. The presence of the Cinnabar Mine on the slopes of Cinnabar Mountain points to the area's mercury mining history, while numerous named drainages like Murderers Creek and McClellan Creek flow through the deep canyons. This 1970s survey illustrates a landscape primarily shaped by topography and water, with established routes such as the Burma Road and various pack trails providing access to high-elevation points like McClellan Mtn and Riley Mountain. The southern edge of the map transitions toward Bear Valley, showing the distinct change from the higher peaks of the Aldrich range to the valley floor. Features like Riley Creek Meadow and Packsaddle Gap highlight the traditional movement patterns through this part of the Blue Mountains region.
