Diablo Dam and the hydroelectric infrastructure of the Skagit River define this corner of the North Cascades. The map details the company towns of Newhalem, Diablo, and Reflector Bar, which were established to support the massive dam projects during the early to mid-20th century. The sheer verticality of the terrain is represented by prominent summits such as Davis Peak, Pyramid Peak, and the uniquely named Paul Bunyans Stump.
