2018 Map of Coleen A-4 NE

About this map

Coleen River winds through the southwestern corner of this survey, carving a distinct hydrological path through the high-latitude terrain of the Alaska interior. The landscape is defined by the Public Land Survey System grids of t28n r23e, t28n r24e, t27n r23e, and t27n r24e, which overlay a series of ridges and valleys in this part of the Yukon-Koyukuk Census Area. The lack of named settlements or roads emphasizes the wild, undeveloped character of this region north of the Arctic Circle, where the topographic contours reveal a complex drainage system tributary to the larger Porcupine River basin.
