Mt Washington and the surrounding Cascade Range form the backbone of this 2024 survey, where the intersection of Linn and Deschutes counties meets the Lane County line. The landscape is defined by its volcanic heritage, with Belknap Crater, Little Belknap, and Black Crater marking the terrain. A dense network of paths, including the Pacific Crest National Scenic Trl and the McKenzie Pass Tour Trl, provides a detailed view of the high-country hydrology near Lava Camp Lake and Big Lake. These trails suggest the area's continued importance for recreation and land management within the Mount Washington Wilderness and Three Sisters Wilderness. The map reveals how the modern wilderness boundaries overlay a complex geography of cinder cones and seasonal water sources like Washington Ponds and Coldwater Spring.
