2020 Map of Port Moller D-4 SW
USGS Topo · Published 2020About this map
Sapsuk River meanders across this Aleutian landscape, defining a complex hydrology of low-lying wetlands and scattered ponds typical of the Bristol Bay drainage. The terrain transitions from these water-heavy flats in the north to increasingly prominent topographic relief in the south, where Peterson Cr flows through rising elevations. This 2020 digital survey reflects a wilderness area defined by its natural watercourses and the Public Land Survey System grids of t50s r78w and t51s r77w, showing a region largely untouched by permanent road infrastructure or settlements.
