About this map

Walker Lake and the Killik River headwaters dominate this wilderness survey, which documents the remote topography of the Brooks Range during the mid-20th century. The map illustrates a complex network of high-altitude passes and glacial lakes, including Ernie Lake and Takahula Lake, which have served as critical landmarks for interior travel. Human activity is represented by the Alatna Portage and a single Cabin near Swan Lake, alongside the naturally occurring Reed Hot Springs.

The landscape is defined by the sharp transition between the Schwatka Mountains and the Endicott Mountains, with prominent summits like Mount Igikpak and the Arrigetch Peaks serving as anchor points. This area, largely contained within the Gates of the Arctic National Park and Wilderness, shows the intricate drainages of the Alatna River and Pingaluk River before large-scale preservation boundaries were finalized.
