2018 Map of Coleen A-4 SE

About this map

Porcupine River and the Coleen River dominate this portion of the Yukon-Koyukuk region, illustrating a landscape defined by the natural movement of major arctic waterways. The Coleen River winds through the northern sections of the survey before reaching its confluence with the larger Porcupine River in the south, a significant junction for understanding the drainage patterns and navigation history of this northern territory. This 2018 survey by the U.S. Geological Survey maps the intricate topography of the surrounding slopes and riverbanks across several townships, including t26n r23e and t26n r24e. The absence of roads or permanent settlements emphasizes the character of the area as a vast corridor for river travel and traditional land use, where the rivers remain the primary landmarks for navigation and geography.
