About this map

Snoqualmie National Forest dominates this landscape in Lewis County, where the high ridges of the southern Cascades define a complex network of drainage basins. The area serves as a significant hydrological divide, where the Deschutes River and Little Deschutes River flow toward the Sound, while the W Fork Little Nisqually River and W Fork Tilton River carve deep valleys through the timberlands. Notable peaks such as Stahl Mtn, Ladd Mtn, and Cougar Mtn ring the central highlands, while The Rockies landmark anchor the southwestern corner.

Water features are tucked into the high-elevation depressions, including Goose Lake and Duck Lake, which sit near the headwaters of the Tilton drainage. The map reveals the intricate system of forest roads and trails that traverse the forest, connecting remote drainages like Winston Cr and Hiawatha Cr. This 2020 survey provides a precise modern look at the landform relief and protected forest boundaries that have shaped the region's conservation and resource history.
