About this map

The S Fork Sulatna River meanders through the heart of this Alaska interior landscape, defining a remote drainage system within the Yukon-Koyukuk region. In this high-latitude terrain, the waterway network is the primary organizing structure of the land, with several smaller tributaries such as May Cr and Little Moose Cr feeding into the larger river valleys. The topography is characterized by the complex drainages of Moose Cr and Sunset Cr, illustrating a wild, unsettled landscape where elevation and water define the character of the terrain. Mapping by the U.S. Geological Survey captures the isolation and natural scale of this northern territory, where no roads or settlements are indicated, emphasizing the undisturbed state of the Alaskan wilderness during the early twenty-first century.
