2018 Map of Coleen A-4 SW

USGS Topo · Published 2018

About this map

Coleen Mtn and Mt Marr dominate this interior Alaskan landscape within the Yukon-Koyukuk region, where the terrain is defined by dramatic elevation changes. This 2018 survey records a remote wilderness divided by the Public Land Survey System into several townships, including t27n r22e and t26n r23e. The map illustrates the topographic complexity of the northern interior before any significant infrastructure or road networks reached this particular sector. This lack of human-made features, such as those typically documented by the Alaska Dept. of Transportation, highlights the area's status as an undisturbed natural environment. The contour lines, derived from the National Elevation Dataset, trace the high ridges and deep valleys that characterize this portion of the Coleen river basin region.
