2019 Map of Iditarod A-1 SW

About this map

The Kuskokwim Mountains dominate this high-latitude terrain, where the topography transitions into the Black Mountains to the south. This 2019 survey captures a remote wilderness straddling the boundary between the Yukon-Koyukuk Census Area and the Bethel Census Area. The map reveals a landscape defined by complex drainage patterns and ridgelines, typical of the interior Alaskan highlands. Given the absence of roads or established settlements, the map provides a precise record of natural contours and hydrology within these prominent mountain ranges, offering researchers a clear view of the land before any modern infrastructure footprint.
