2016 Map of Survey Pass B-1 SW

USGS Topo · Published 2016

About this map

Gates of the Arctic National Park encompasses this entire sub-quadrangle, capturing a landscape of high-altitude drainages and steep topography in the northern reaches of Alaska. The terrain is defined by the headwaters of Tobuk Cr, which carves southward through the central valley, and the Iniakuk River, which flows through the southeastern quadrant. This 2016 survey illustrates a purely wilderness environment, devoid of roads, settlements, or structures, reflecting the federally protected status of the land. The map provides precise contour data for the drainages and ridges within Township 23 North and Township 22 North, documenting the hydrological patterns of the Koyukuk watershed before recent shifts in Arctic climate and permafrost stability could alter these remote watercourses.
