2019 Map of Iditarod D-5 SW

About this map

The Big Yetna River flows through the northern reaches of this interior landscape, defining a wetland environment of intricate drainage and low-lying terrain. To the west, the Little Yetna River winds through the flats, illustrating the remote and water-heavy nature of the Yukon-Koyukuk region. This 2019 survey documents the complex hydrology of the area, where the river systems are the dominant natural features. The map provides a clear look at the Public Land Survey System grid, including townships T32n R49w and T31n R48w, which organize this largely unpopulated wilderness. While the region lacks roads or settlements, the detailed contouring and hydrographic data reflect the shifting nature of these subarctic river basins.
