2018 Map of Coleen B-1 NE
USGS Topo · Published 2018About this map
The Porcupine River carves a deep, serpentine path through this interior landscape of the Yukon-Koyukuk Census Area. This segment of the river, located just south of the Arctic Circle, exhibits a complex pattern of incised meanders that reveal the dramatic elevation changes of the surrounding terrain. Joining the system from the northwest, White Mountain Cr flows through the high valleys of the Davidson Mountains, providing a primary drainage for the central portion of the quadrangle. The map details the Public Land Survey System grid, specifically identifying t30n r30e and surrounding townships, which were established to organize these remote northern territories. The lack of man-made structures or improved roads underscores the isolation of this river corridor in the early 21st century.
