About this map

The Snoqualmie National Forest dominates this landscape in King County, defined by its complex network of alpine lakes and dramatic elevation changes. Centered on Lake Philippa, the area features numerous high-altitude water bodies including Upper Loch Katrine, Marten Lake, and Honey Lake. The drainage system is anchored by the Middle Fork Snoqualmie River and the Pratt River, which carve deep valleys between prominent peaks like Quartz Mtn, Bessemer Mtn, and Garfield Mtn.

Transport through this protected wilderness is limited to rugged forest service routes such as Sunday Creek Rd and NFD 5600 Rd. These roads provide the only vehicle access into a region otherwise defined by sharp ridges and steep drops, such as the northern Devils Canyon. The density of named lakes and mountains highlights the area's importance for resource management and backcountry recreation within the national forest system.
