2018 Map of Big Delta B-1 SE
USGS Topo · Published 2018About this map
Black Mtn dominates the western portion of this high-altitude landscape in the Unorganized Borough, situated within the Tanana Valley watershed. This 2018 survey documents a region defined by its complex drainage patterns, where Divide Cr and Boulder Cr navigate the steep elevation changes. The presence of Antimony Cr in the northern reaches hints at the mineral-rich geology often associated with this part of Alaska, while other seasonal and perennial flows like Summit Cr and Johnson Cr further carve the terrain. The map provides a detailed view of the Public Land Survey System grid across portions of Townships 6, 7, and 8 South, offering a precise record of the land divisions in this interior Alaskan wilderness.
