Snoqualmie National Forest dominates this section of Lewis County, where a complex network of forest development roads provides access to the high ridgelines and timbered basins. The terrain is defined by prominent peaks including Stahl Mtn, Ladd Mtn, and Cougar Mtn, while the southern portion of the quadrangle is anchored by the geological formation known as The Rockies. This area serves as a significant drainage divide for several major water systems, including the Deschutes River and the Little Nisqually River, which carve through the landscape alongside smaller tributaries like Rockies Cr and Scatter Cr. The presence of small high-country bodies of water such as Goose Lake and Duck Lake suggests the glacially influenced topography characteristic of this part of the Cascades. The extensive road system, including Nat For Dev Rd 71 and Nat For Dev Rd 74, reflects the ongoing management and resource extraction history within the national forest boundaries.
