2018 Map of Black River B-2 SW

USGS Topo · Published 2018

About this map

Grayling Fork Black River dominates the southwestern portion of this interior Alaskan terrain, where the meandering watercourse carves a complex path through low-lying marshlands. This 2018 survey reveals the intricate hydrography of the Grayling Fork Black River valley, defined by numerous oxbows and seasonal channels that reflect the region's dynamic hydrology. The topography north and east of the river transitions into rising uplands, providing a clear visualization of the drainage patterns within the eastern reaches of the Yukon-Koyukuk Census Area. This remote wilderness is meticulously partitioned by the Public Land Survey System, with the map delineating the boundaries of t18n r27e, t18n r28e, t17n r27e, and t17n r28e as part of the broader administrative grid of the Alaskan interior.
