The Lewis River and the massive reservoir of Lake Merwin Elevation 239 dominate this 1970s landscape on the border of Cowlitz and Clark Counties. The presence of the Merwin Dam, its Powerhouse, and a nearby Substation highlight the significance of hydroelectric power in the region's development. Smaller settlements such as Ariel, Etna, and Highland are scattered throughout the hills, connected by a network of rural routes like Dall Road and Peart Road.
