2018 Map of Christian B-4 SW

USGS Topo · Published 2018

About this map

The Yukon-Koyukuk region of northern Alaska is represented here through the structured grid of the Public Land Survey System, specifically within the townships of T29n R8e, T29n R9e, T28n R8e, and T28n R9e. This 2018 survey reveals a terrain defined primarily by its natural contours and the absence of established modern infrastructure or named settlements. The map serves as a primary source for understanding the remote topography of the Christian River drainage area, where high-resolution elevation data provides a baseline for the land before further development or significant environmental change. The reliance on township and range markers highlights the foundational role of federal surveying in defining these northern interior lands.
