2020 Map of Mossyrock

About this map

Mossyrock and the surrounding Lewis County countryside are defined by the convergence of mountain terrain and the waters of the Cowlitz River valley. This 2020 topographic record shows the expanded footprint of Riffe Lake, which dominates the eastern landscape alongside Swofford Pond in the Swofford Valley. The map detail identifies numerous small residential clusters including Ajlune, Swofford, and Harmony, alongside family and community landmarks like Dunn Cem, Doss Cem, and Saint Yves Catholic Cem. To the north, the terrain climbs toward Bremer Mtn and the Snoqualmie National Forest, where the Tilton River flows through narrow canyons. The proximity of these upland forests to the agricultural and settled lowlands illustrates the region's enduring character as a gateway between the timberlands and the river valley.
