2018 Map of Coleen D-5 SW

About this map

The Sheenjek River meanders through the western corridor of this interior Alaska wilderness, establishing the primary drainage pattern for the surrounding highlands. This 2018 survey detail shows a landscape defined by sharp topographic relief and glacial hydrology, where the river valley creates a stark contrast to the upland terrain. The map serves as a technical record of the public land survey system divisions, including t35n r19e and t34n r19e, which are plotted against the natural contours of the Yukon-Koyukuk region. Researchers and land managers can trace the exact course of the river as it shifts through its floodplain, providing a baseline for understanding the shifting environmental conditions and land boundaries in one of the most northern reaches of the United States.
