About this map

Walker Lake dominates the central landscape of this interior Alaskan survey, a massive body of water that feeds the southward flow of the Kobuk River. Positioned above the Arctic Circle, this 1980s map documents the region following the establishment of federal protections under the Alaska National Interest Lands Conservation Act. The map captures the meeting of several administrative designations, including the Gates of the Arctic National Park, its designated Wilderness, and the National Preserve.

Smaller geographic details include Swan Island within the lake and the Kichaiakaka Creek drainage to the east. The southern portion of the sheet is marked by the Helpmejack Hills, showing a wilderness terrain completely devoid of roads or trails. This provisional survey provides a precise record of the hydrography and elevation contours that defined this protected corridor before modern shifts in the arctic environment.
