2018 Map of Black River A-5 SW

About this map

The Alaskan wilderness within the Yukon-Koyukuk Census Area is captured here through detailed topographic contouring and hydrographic data. This portion of the Black River region is defined largely by its township and range subdivisions, specifically T15n R20e, T15n R21e, T14n R20e, and T14n R21e. The landscape is characterized by a dense network of small ponds and wetlands, as identified by FWS National Wetlands Inventory data from the early 1980s. The intricate terrain, illustrated by ten-foot contour intervals, reveals a complex drainage pattern that is typical of this subarctic environment. While devoid of named settlements or roads, the map serves as a precise record of the physical geography and public land survey system grid in a remote section of the interior.
