2016 Map of Survey Pass A-4 NW
USGS Topo · Published 2016About this map
Gates of the Arctic National Park encompasses the southeastern portion of this landscape, marking a protected wilderness in the Alaska-Northwest Arctic Borough. The terrain is defined by the winding course of the Reed River, which meanders through the central valleys and collects tributaries like Inyulak Cr from the surrounding high country. This 2016 survey illustrates the hydrography of the Brooks Range foothills, showing how the river systems dictate the layout of this remote region. The map provides a precise look at the township and range divisions, including t21n r18e and t20n r18e, offering a detailed record of land management boundaries within one of the nation's most isolated national park units.
