2018 Map of Coleen C-3 NW

About this map

The Coleen River flows through the northwestern reaches of this subarctic landscape in the Yukon-Koyukuk Census Area. This 2018 survey reveals a terrain defined by extensive wetlands and thaw lakes typical of the interior Alaskan wilderness, where the slow-moving Coleen River meanders across the coastal plain. In the central and eastern portions of the quadrangle, the drainage of Dorothy Cr creates a network of smaller channels and pools. The map illustrates the Public Land Survey System grid across multiple townships, including t34n r23e and t33n r24e, marking a territory largely devoid of permanent human infrastructure or settlements. This document provides a clear record of the area's natural hydrology and topographical contours at a 10-foot interval, capturing the subtle elevations of this remote river basin.
