2015 Map of Nulato D-5 NW

About this map

The Gisasa River winds through the northwestern corner of this interior Alaskan landscape, providing a rare hydrological anchor in a territory defined by high ridges and deep drainages. This 2015 survey, published by the U.S. Geological Survey, illustrates the complex topography of the Yukon-Koyukuk region before it descends toward larger river valleys. The land is partitioned by the Public Land Survey System into townships such as T6s R2e and T6s R3e, revealing a wilderness largely devoid of human infrastructure or permanent settlements. The contour lines trace a series of steep summits and interconnected valleys, offering a primary resource for understanding the natural drainage patterns and land-use boundaries in this portion of the Nulato quadrangle.
