2018 Map of Coleen A-5 NW

About this map

The Alaskan wilderness in the Yukon-Koyukuk Census Area is meticulously charted in this 2018 survey, focusing on the remote intersection of T28n R19e, T28n R20e, T27n R19e, and T27n R20e. This topographic study reveals a landscape dominated by complex hydrography, featuring a high density of small lakes and extensive wetland systems characteristic of the far north. The terrain transitions from low-lying marshy basins to isolated, rounded summits, with contour lines illustrating the subtle elevation changes that dictate the drainage patterns across these township boundaries. While devoid of named settlements or infrastructure, the map provides an essential baseline for understanding the natural geography and land divisions within this undeveloped interior region.
