2019 Map of Iditarod D-4 SE

About this map

The Kuskokwim Mountains dominate this 2019 survey, defining a landscape of high ridges and narrow drainage basins in the interior of Alaska. This specific quadrangle captures a remote section of the Yukon-Koyukuk region where the topography rises sharply from the valleys of Glacier Cr and First Chance Cr. The map's high-resolution contour work reveals the complex serrated ridges and summits that characterize this part of the range, offering a precise view of the terrain before any significant human development or road infrastructure reached these reaches. Without settlements or industrial sites printed on the sheet, the focus remains entirely on the natural hydrology and the massive scale of the mountain system, making it a critical reference for understanding the untouched wilderness of the Alaskan interior in the early 21st century.
