About this map

The John Swallow Grave stands as a solitary human marker in this high-elevation landscape along the border of Linn and Jefferson counties. Situated in the heart of the Mount Jefferson Wilderness, the area is defined by a dense network of volcanic features and alpine water bodies. The massive Marion Lake dominates the western slopes, fed by glacial runoff and drained by Marion Falls. To the south, the Eight Lakes basin, including Blue Lake and Jorn Lake, illustrates the post-glacial topography of the High Cascades.

Transportation is limited to primitive routes, most notably the Pacific Crest National Scenic Trail, which traverses the ridge lines between peaks like South Cinder Peak and Rockpile Mtn. This survey captures the wilderness character of the Willamette National Forest and Deschutes National Forest during the late 1980s, documenting the intricate drainage patterns and lava-formed ridges like Lizard Ridge and Sugar Pine Ridge before modern mapping transitions.
