1990 Map of Survey Pass C-5

About this map

Gates of the Arctic National Park dominates this subarctic landscape, where the Continental Divide winds through the northern reaches of the Northwest Arctic Borough. The hydrology of the region is defined by the massive drainage systems of the Noatak River and the Alatna River, which are fed by numerous tributaries including Twelvemile Creek, Portage Creek, and Anorat Creek. This 1990 provisional edition provides a precise look at the mountain peaks and drainage basins of the Gates of the Arctic Wilderness as they were surveyed from aerial photography in the late 1970s and early 1980s. Notable landforms like Oyukak Mountain stand as primary reference points in a vast network of unnamed peaks and ridges, illustrating the untouched character of the Brooks Range before more modern ecological shifts. The absence of roads or trails emphasizes the region's status as a protected wilderness area.
