Mount Washington stands as the central landmark of this high-altitude survey, marking the intersection of the Willamette National Forest and Deschutes National Forest. The map documents a landscape defined by volcanic geology and historical transit corridors through the Cascade Range. Significant geological features like Belknap Crater, Little Belknap, and Black Crater punctuate the terrain, illustrating the dramatic volcanic history of the region. The map traces the modern path of the Pacific Crest National Scenic Trail as it winds past Washington Ponds and Big Lake. Historically significant routes are also visible, including the Old Santiam Wagon Rd and the Toll Station Rd, which follow the northern contours of the peaks. At the southern edge, the McKenzie Hwy ascends toward McKenzie Pass, passing through basaltic fields near Lava Camp Lake and the overlook at Windy Point.
