2019 Map of Iditarod A-6 NE

About this map

The Iditarod River meanders through this interior Alaska landscape, creating a complex network of oxbows and wetlands in the southeastern portion of the quadrangle. This 2019 survey, produced by the U.S. Geological Survey, focuses on the undeveloped terrain of the Yukon-Koyukuk Census Area. The topography is defined by significant elevation changes, with ridges rising between the drainage basins of the t25n r51w and t24n r51w townships. The map provides a detailed record of the natural hydrology before any modern infrastructure, documenting the intricate flow patterns of the river as it cuts through the undulating interior. It serves as a baseline for understanding the geomorphology of this remote region, where the landscape remains dominated by natural watercourses and topographic contours rather than human settlements.
