2018 Map of Fort Yukon A-3 NE

About this map

Birch Creek meanders heavily through this portion of the Yukon-Koyukuk Census Area, creating a complex network of oxbow lakes and abandoned river channels. This wetland landscape in northern Alaska, captured in 2018, is defined by the shifting course of the water across the flat terrain. Further south, Discovery Cr flows through the lower reaches of the quadrangle. The map highlights the vast stretches of marsh and water-saturated soil that characterize this subarctic interior region, where seasonal water levels dictate the shape of the land. Public land surveys such as t16n r12e and t16n r13e provide the structural grid over this predominantly natural environment, where the river's constant movement remains the primary sculptor of the local topography.
