2016 Map of Survey Pass A-1 NW

USGS Topo · Published 2016

About this map

The Alatna River snakes through the western portion of this landscape, its wandering oxbows and side channels defining the low-lying valley floor. This 2016 survey by the U.S. Geological Survey captures the intricate drainage patterns of the region, where the river's path is mirrored to the east by the smaller Tobuk Creek (also labeled Tobuk Cr). The terrain is dominated by the transition from riverine wetlands to the rising slopes of the Brooks Range foothills, with Iniakuk Lake situated in the southeastern corner. This map provides a clear record of the hydrography in the Yukon-Koyukuk region, illustrating how water shapes the interior Alaskan wilderness.
