Gates of the Arctic National Park and Noatak National Preserve meet along a remote boundary in the Northwest Arctic Borough, where the high-latitude drainage patterns of the Brooks Range are meticulously documented. The landscape is defined by the headwaters and winding path of Tunukuchiak Creek, which flows through a series of steep topographic contours and glacial valleys. This 2016 survey emphasizes the protected wilderness status of the region, showing a terrain devoid of permanent settlements or modern road infrastructure. Instead, the map provides a look at the natural hydrology and elevation of these contiguous federal lands, highlighting the transition between two of Alaska's most significant conservation areas.
