2020 Map of Marshall A-5 NW

About this map

Aropuk Lake dominates the central landscape of this western Alaska region within the Bethel Census Area. The terrain is defined by a complex network of wetlands and water bodies, characteristic of the Yukon-Kuskokwim Delta region. The map details the Public Land Survey System grid across four townships, including t13n r81w and t12n r81w, illustrating the geometric division of this roadless wilderness. This 2020 survey integrates data from several decades, including hydrography and wetland layers that trace the shifting aquatic environment of the tundra. The absence of permanent settlements or infrastructure highlights the isolation of this expansive wetland complex, where the vast water footprint of Aropuk Lake serves as the primary geographic landmark for researchers and land managers.
