2018 Map of Coleen B-1 SW

USGS Topo · Published 2018

About this map

The Porcupine River carves a deep, winding path through the interior of the Yukon-Koyukuk Census Area, defining the topography of this subarctic landscape. Flowing from east to west, the river passes through the Upper Ramparts, a section of the corridor marked by distinctive elevation changes and sharp contour intervals. South of this main waterway, the Campbell River meanders across the lower terrain before its eventual confluence beyond the sheet's western boundary. This survey by the U.S. Geological Survey captures a wild and unpopulated expanse of the eastern Alaska wilderness, where the primary movement is dictated by these significant drainage systems. The landscape is dominated by a series of high ridges and narrow valleys, reflecting a geography largely untouched by permanent settlement or infrastructure development.
