About this map

John Swallow Grave stands as a solitary historical marker in this high-altitude wilderness, situated between Midget Lake and Sad Lake. The landscape is defined by the crest of the Cascades, where the boundary between Linn Co and Jefferson Co follows a dramatic ridgeline. This divide separates the Willamette National Forest to the west from the Deschutes National Forest to the east, with the Pacific Crest National Scenic Trail serving as the primary north-south artery through the volcanic terrain.

Water dominates the topography, from the expansive Marion Lake and the cluster of the Eight Lakes Basin to the high alpine waters of Jefferson Lake beneath Cathedral Rocks. Historical transit routes like Minto Pass and the Old Summit trail suggest long-standing corridors through the mountains. Significant peaks such as Rockpile Mtn, N Cinder Peak, and S Cinder Peak punctuate the ridges, while the Bingham Basin and Bear Valley provide distinct glacial depressions in the high country.
