About this map

Summit Lake and its surrounding high-country watersheds define this mid-century survey of the Oregon Cascades. The map shows a landscape undergoing significant hydroelectric and recreational development, most notably at Lemolo Lake where a dam, spillway, and generator are marked along the North Umpqua River. This infrastructure appears alongside temporary structures like the Construction Camp and a gaging station, documenting the transformation of the river for power.

Wilderness access is illustrated through a network of primitive forest roads and trails, including the Skyline Trail and Pioneer Way, which connect remote outposts such as Emigrant Forest Camp and Beaver Marsh. The terrain is punctuated by distinctive volcanic features like Cowhorn Mtn, Sawtooth Mtn, and the evocatively named Dread and Terror Ridge. The presence of the Crescent Lake Organization Camp and several other forest camps highlights the region's mid-century identity as a destination for seasonal labor and backcountry recreation.
