About this map

Snoqualmie National Forest dominates this landscape, which is defined by its dramatic hydraulic features and high-elevation topography. The eastern half of the map is anchored by the substantial reach of Spada Lake and the Sultan Basin, while the Sultan River Canyon cuts through the northern terrain. This area demonstrates a complex network of forest access roads, such as Corona Mine Rd and Sultan Basin Rd, which provide passage through the steep grades of Sultan Ridge and toward notable viewpoints at Olney Pass.

The southwestern portion reveals the source of the Wallace River, including the iconic Wallace Falls and Wallace Lake. These water systems, alongside Jay Lake and the N Fork Wallace River, illustrate the drainage patterns of the western Cascade foothills. Hikers and researchers can trace the Wallace Lake Via Upper Falls route, which connects the lower river valley to the secluded alpine lakes, showcasing how recreational and conservation interests have shaped the modern footprint of Snohomish County.
