Broad Pass serves as a critical corridor through the Alaska Range, anchoring the geography of this survey. The Parks Highway serves as the primary artery, paralleling a series of significant alpine water bodies including Summit Lake, Mirror Lake, and Edes Lake. Near the northern boundary, the settlement of Cantwell sits just outside the expanse of Denali National Park, marking a transition point between the protected wilderness and the transit routes heading south. The southern portion of the map is defined by the drainage of the Middle Fork Chulitna River, while the high-altitude settlement of Summit is supported by the Summit Airport, highlighting the importance of aviation in this interior Alaskan landscape. This area represents a vital drainage divide, where Cantwell Creek flows toward the north and the Coal Cr system begins its descent toward the southern coast.
