1988 Map of Marion Lake

About this map

John Swallow Grave stands as a solitary human marker in this high-altitude landscape of the Cascades, situated west of the Linn and Jefferson County line. The map detail reflects the region as it was field-checked in 1961, documenting the volcanic and glacial features of the Mt Jefferson Wilderness. A dense network of water bodies, including the large Marion Lake and the high-elevation Eight Lakes Basin, dominates the topography between Willamette National Forest and Deschutes National Forest. The presence of the Pacific Crest National Scenic Trail winding past North Cinder Peak and Rockpile Mtn highlights the area's significance for early wilderness recreation. Notable geological landmarks like The Table and Forked Butte sit among ancient lava flows, providing a detailed record of the terrain before late 20th-century shifts in forest management.
