2017 Map of Beaver A-1 SW

About this map

The Alaskan interior within the Yukon-Koyukuk region is defined here by the intersection of four major survey townships. This 2017 study focuses on the transition between T15N R1E, T15N R2E, T14N R1E, and T14N R2E, where the landscape is dominated by a complex network of wetlands and seasonal ponds. The absence of human-named settlements or infrastructure highlights the isolation of this terrain, characterized by undulating elevation contours and the dense hydrological patterns of the subarctic. Surveyed by the U.S. Geological Survey, the map provides a precise record of the natural topography and drainage before potential shifts in the permafrost or hydrological boundaries. This specific quadrangle remains an essential resource for understanding the remote wilderness and land management boundaries in this part of northern Alaska.
