2018 Map of Black River D-1 SE

About this map

The international border between the United States of America and Canada defines the eastern edge of this remote wilderness in the Yukon-Koyukuk Census Area. This 2018 survey emphasizes the extreme topography of the region, where high ridges and steep valleys dominate the terrain within the Public Land Survey System divisions of T24n R30e, T23n R31e, and T22n R30e. The landscape is entirely undeveloped, lacking named roads, settlements, or structures, reflecting the primitive state of the northern interior. This map is a primary resource for understanding the pure physical geography along the 141st meridian, providing a precise record of the natural elevations and drainage patterns before any significant human footprint reached this section of the frontier.
