2016 Map of Tanacross B-4 NW

About this map

The Tanana River meanders across this northern landscape, carving a complex series of oxbows and channels through low-lying terrain. As documented in this 2016 survey, the river serves as the dominant hydrological force, creating a braided network of water and wetlands that characterize much of the southern half of the quadrangle. The map highlights the shifting path of the river, where seasonal changes and glacial runoff from distant ranges constantly reshape the shoreline and sandbars. Beyond the river valley, the terrain transitions into a grid of public land subdivisions, including t19n r13e and t20n r14e, which define the administrative boundaries of this interior Alaskan wilderness. This survey is a precise record of the natural topography and waterway alignment in an area largely defined by its lack of permanent settlements or infrastructure.
