2019 Map of Iditarod B-1 SW

About this map

The Nunsatuk River meanders through the southeastern portion of this terrain, marking the primary drainage in an otherwise unpopulated landscape. This 2019 survey, produced by the U.S. Geological Survey, illustrates a remote section of the Alaska interior within the Yukon-Koyukuk Census Area. The map is defined by its complex elevation contours and the absence of established roads or structures, reflecting a wilderness state. Surveyors focused on the hydrography and public land boundaries, specifically tracking the corners of t26n r39w, t26n r38w, t25n r39w, and t25n r38w. Researchers and geographers will find a precise record of the natural topography as it stood in the early twenty-first century, before any modern infrastructure altered the drainage patterns.
