Mossyrock and the surrounding Lewis County settlements stand at the heart of this hydroelectric landscape along the Cowlitz River. The geography is dominated by the massive impoundments of Riffe Lake and Mayfield Lake, held back by the engineered heights of the Mossyrock Dam and Brian Dam. This survey documents the modern footprint of the valley, where smaller communities like Ajlune and Swofford are situated near the fingers of the reservoirs. To the north, the Tilton River carves through steeper terrain, passing the settlement of Bremer and the high point of Bremer Mountain. For local history researchers, the map traces the intricate network of forest roads and rural routes such as Burton Burres Rd and Damron Rd that connect these waterside towns to the forested uplands of Bear Canyon and Bellicum Peak.
