2018 Map of Black River A-4 SE

About this map

Bear Mtn dominates the eastern-central landscape of this interior Alaskan wilderness, serving as the topographical anchor for the surrounding high-altitude terrain. The map details the headwaters and drainage patterns of the region, specifically tracking Bear Mountain Cr as it flows from the southwestern slopes. The absence of roads or permanent structures reflects the extreme isolation of the Yukon-Koyukuk Census Area, where the landscape is defined primarily by steep elevation changes and natural watercourses. Surveyed with 40-foot contour intervals, this sheet provides a detailed look at the physical geography between the T14N and T15N township lines, capturing a pristine environment before any modern development or infrastructure reached this part of the Black River region.
