Mount Igikpak and the Arrigetch Peaks define the high terrain of the central Brooks Range on this mid-century topographic record. The map covers a vast network of headwaters where the Nigu River and Killik River flow north toward the Arctic, while the Alatna River and Kobuk River systems drain to the south. This area is characterized by high-elevation crossings like Survey Pass and Kutuk Pass, which served as critical transit points through the Endicott Mountains and Schwatka Mountains. Significant water bodies such as Walker Lake and Iniukuk Lake appear at the base of the southern slopes. Apart from a few isolated structures, including a Cabin and a Portage point on the Alatna, the map shows a landscape largely shaped by its hydrography and dramatic relief, including family-named landmarks like Papik Mtn and Dalimaloak Mountain.
