Snoqualmie National Forest dominates this upland section of Lewis County, where the headwaters of several major regional drainage systems begin their descent. The terrain is defined by significant high points including Lookout Peak, Huckleberry Mtn, and Bald Mtn, which separate the various watersheds. Notably, the map captures the origin of the Deschutes River and its W Fork, alongside the Skookumchuck River and the S Fork Newaukum River. Central to the landscape is Newaukum Lake, a high-elevation water body tucked between steep ridges. The southern portion of the quadrangle drops into Bear Canyon and touches the N Fork Tilton River, showcasing the complex hydrology of the Pacific Northwest. This 2020 update provides a precise look at the forest road network and topographic relief in a region where forestry and watershed management are the primary human imprints.
