1956 Map of Coleen A-4

About this map

Coleen River winds through this subarctic landscape where the southern reaches of the Brooks Range meet the expansive Yukon Flats. Surveyed in the mid-1950s, the terrain is dominated by prominent peaks such as Coleen Mountain and Mount Marr, which rise above the river valleys. The hydrology of the region is defined by the confluence of the Coleen and the Porcupine River, the latter of which provides a major drainage route through the southeastern corner of the quadrangle near the landmark at Burnt Paw. Human presence is marked by a single Winter Trail in the northern sector, reflecting the seasonal mobility required in this environment. Significant portions of the land are managed under the Arctic National Wildlife Refuge and the Yukon Flats National Wildlife Refuge, highlighting the conservation status of these river corridors and mountain ranges.
