2018 Map of Coleen A-2 SW
USGS Topo · Published 2018About this map
David Cr and Rat Cr define the hydrological character of this portion of the Coleen River drainage. This 2018 survey reveals a terrain defined by subtle elevation changes and the absence of human infrastructure, consistent with the remote interior of the Yukon-Koyukuk Census Area. The topography is meticulously captured by the U.S. Geological Survey using modern National Elevation Dataset information, showing the complex drainage patterns where David Cr flows through the central and southern sections of the quadrangle. The map is primarily an exercise in topographic precision, illustrating the natural landforms of the Porcupine River region before any significant development or road networks were established.
