2018 Map of Black River A-5 NW

About this map

The interior landscape of the Yukon-Koyukuk Census Area is meticulously charted in this 2018 survey, focusing on a region of complex hydrography and wetland systems. The terrain is defined by the Public Land Survey System grids of T16n R20e and T16n R21e, where numerous small lakes and meandering water bodies illustrate the dynamic nature of the Alaskan wilderness. This specific area, part of the larger Black River region, remains largely undeveloped, lacking roads or permanent settlements as of the late 2010s. The map provides a high-resolution view of the local drainage patterns and elevation contours, which are essential for understanding the seasonal changes in this subarctic environment. To the south, the survey continues through T15n R20e and T15n R21e, capturing the subtle shifts in the muskeg and tundra landscape that characterize this remote portion of the state.
