Lewis River and the small settlement of Cougar define the southern reaches of this landscape, where the waters of Yale Lake and Merrill Lake dominate the terrain. This modern survey illustrates the complex geography of the volcanic region, showing the intersection of the Gifford Pinchot National Forest and the Mount Saint Helens National Volcanic Monument. The rugged hydrography is detailed through features like Kalama Falls on the Kalama River and the steep drainages of Christmas Canyon and Cougar Creek. Transportation and access for forestry and recreation are traced along the Natl Forest Develop Road 81 Rd and Lewis River Rd. Significant vertical relief is marked by summits such as Cinnamon Peak and the vantage of Cooney Point overlooking the reservoir system.
