Kromona Mine and several Quarries indicate the industrial extraction occurring within the high-elevation terrain of Snoqualmie National Forest during the late 1980s. The landscape is defined by its complex drainage systems, including the Sultan River and its multiple branches, which feed into the large reservoir of Spada Lake. The map reveals a network of alpine water bodies such as Big Greider Lake, Little Greider Lake, and Boulder Lake, which characterize the glacial geography of the Cascade Range. Notable summits like Mt Stickney, Prospect Peak, and Red Mtn rise above Ragger Ridge, illustrating the steep vertical relief of the Snohomish County backcountry. The presence of a Campground near Boulder Creek reflects the area's transition toward recreational utility alongside established mining interests.
