Merrill Lake and the northern reaches of Yale Lake dominate this portion of the Cascade foothills, where the small community of Cougar serves as a gateway to the volcanic landscape. The map details the transition from the Gifford Pinchot National Forest to the waters of the Lewis River, tracing the river's path through engineered features like the Swift Number Two Forebay. High points like Cinnamon Peak overlook a complex network of forest development roads and local routes such as Old Lake Merrill Rd and Dog Creek Rd. The geography is defined by narrow canyons and rushing water, including Christmas Canyon and the Kalama Falls on the Kalama River. This survey captures the region's character as a hub for timber management and hydroelectric power, marked by the distinct boundary between Cowlitz and Clark Counties.
