Lake Cushman and the surrounding peaks of the Olympic Mountains dominate this high-elevation landscape along the border of Jefferson and Mason Counties. The map documents a heavily protected wilderness area divided between Olympic National Park and Olympic National Forest, where steep ridgelines like Sawtooth Ridge separate drainage basins. This modern topographic record shows the intricate network of glacial lakes and high-alpine tarns, including the Black and White Lakes, Flapjack Lakes, and Murdock Lakes. These water bodies feed the dramatic descent of the Hamma Hamma River and the North Fork Skokomish River. The map is particularly useful for tracking access routes into the backcountry, such as the Dry Creek Trl and various forest roads like Nat For Dev Rd 24, which provide the primary entry points for exploring summits like Mount Skokomish and Mt Rose.
