2018 Map of Coleen A-2 SE

About this map

This high-altitude landscape in the Yukon-Koyukuk Census Area is defined by its dramatic topographic relief and remote northern character. The survey covers several major township divisions including T26n R27e and T26n R28e, where steep ridgelines and deep drainage basins are meticulously charted. Without established roads or named settlements, the map focuses on the physical geography of the Alaskan interior, showing a complex network of seasonal watercourses and high summits that climb above 2,200 feet. The detailed contour intervals provided by the U.S. Geological Survey illustrate the sharp transitions between valley floors and the towering ridges of T27n R27e and T25n R28e. For the naturalist or cartographic researcher, this sheet offers a precise view of the untouched wilderness in a region where human infrastructure has not yet left a permanent mark.
