About this map

Pacific Crest National Scenic Trail hikers in the mid-1980s would have traversed a high-altitude landscape where the boundaries of four national forests meet. This survey details the complex hydrography of the High Cascades, centering on the massive Summit Lake and the western reach of Crescent Lake. The map reveals a high concentration of backcountry recreation sites established during this era, including Whitefish Horse Camp, Spring Campground, and several picnic areas like Tranquil Cove Picnic Area.

Elevated terrain is anchored by Cowhorn Mtn and Sawtooth Mtn within the Calapooya Mountains. The map serves as a record of the region's wilderness character before modern expansion, highlighting dozens of high-mountain waters such as Timpanogas Lake, the Windy Lakes, and Indigo Lake. The convergence of the Deschutes, Willamette, and Umpqua national forests around the Diamond Peak Wilderness underscores the area's significance for federal land management and conservation.
