The South Fork McKenzie River and the Middle Fork Willamette River dominate the drainage patterns of this high-elevation landscape within the Willamette National Forest. This mid-century survey captures a network of fire lookouts and forest management infrastructure essential to the region's timber and conservation history, including the Rebel Rock Lookout, Grasshopper Mtn Lookout, and Mule Mtn Lookout. The eastern portion of the sheet is defined by the high-country lakes of the Three Sisters Wilderness Area, featuring the expansive Waldo Lake and a chain of smaller alpine bodies such as Upper Erma Bell Lake and Lake Kiwa.
