Sulphur Hot Springs and the surrounding wilderness of the Mt Baker National Forest characterize this mid-1960s study of the Cascades. The landscape is defined by the steep drainage basins of the Suiattle River and its major tributaries, including Downey Creek and Sulphur Creek. Human presence is limited to remote outposts and recreation points like the Downey Creek Campground and Sixmile Shelter, reflecting the high-elevation backcountry accessible only by trail or forest road. High-altitude landmarks such as Mount Buckindy, Green Mountain with its designated Lookout, and Downey Mountain dominate the terrain, which is dotted with alpine water bodies like Bench Lake and Pilot Lake. An Indefinite Boundary marks the division between Skagit and Snohomish counties in this high-relief area where natural features dictate the flow of travel and the placement of few surveyed improvements.
