About this map

The Gates of the Arctic National Park and its corresponding Gates of the Arctic Wilderness dominate this 1986 survey of Northern Alaska. This map documents a roadless landscape defined by its complex drainage systems, where the south-flowing Iniakuk River and Tobuk Creek carve through steep topographic contours.

The presence of the Kateel River Meridian East Boundary provides a critical surveying anchor for this section of the Yukon-Koyukuk region. Named water features like Ernie Lake and the Nahtuk River serve as the primary landmarks in an area otherwise characterized by its lack of human infrastructure, reflecting the conservation status established by the Alaska National Interest Lands Conservation Act just years prior to this publication.
