About this map

Spiral Butte and the volcanic landscape of the Cascade Range define this high-altitude survey along the Yakima and Lewis County line. The area is a dense network of subalpine basins and glacial features, notably the Twin Sisters Lakes and the cluster of water bodies including Dumbbell Lake, Cramer Lake, and Shellrock Lake. These alpine lakes are situated within the William O. Douglas Wilderness, illustrating the region's preservation as a primitive backcountry area in the late 20th century.

Lower elevations show the infrastructure of mountain recreation and water management, particularly around the northern tip of Rimrock Lake and the adjacent Clear Lake. The presence of the Dog Lake Campground and Camp Dudley Campground near the Tieton River headwaters highlights the long-standing role of the Snoqualmie National Forest in supporting outdoor tourism. Notable landmarks such as Tumac Mountain and the prominent Russell Ridge provide significant topographic context for backcountry travelers and local history researchers.
