2017 Map of Nulato D-6 NW

About this map

Gisasa River winds through the southeastern corner of this Alaskan interior terrain, where the water levels and drainage patterns of the Yukon-Koyukuk region are documented in detail. The landscape is defined by the narrow valley of Arvesta Cr, which flows southward through the central part of the quadrangle. As a modern 2017 survey, the map captures the wilderness character of the western Alaska interior, reflecting the Public Land Survey System grids for several townships, including t6s r1w and t7s r1w. The contour lines illustrate the intricate elevation changes between the creek drainages and the surrounding uplands, providing a high-resolution look at the hydrography before it meets the larger river systems of the region.
