2018 Map of Black River A-1 SW

USGS Topo · Published 2018

About this map

Steamboat Mtn dominates the northwestern portion of this terrain in the Yukon-Koyukuk Census Area, rising above a landscape defined by its intricate drainage patterns. The meandering path of Bull Creek bisects the lower elevations, cutting through the interior wilderness as it flows southward through the eastern half of the township boundaries. This 2018 survey illustrates the complex natural topography of the Alaska interior, where the land is strictly delineated by the Public Land Survey System grids of T15N and T14N. The absence of roads or established settlements emphasizes the remote character of this region, where the primary landmarks are the relief of the mountains and the seasonal flow of the creeks.
