2020 Map of Port Moller A-3 NE

About this map

Unga Island, the largest of the Shumagin Islands in the Aleutians East Borough, dominates this coastal survey. The southern landscape is defined by the deep indentation of Acheredin Bay, which opens into the Pacific Ocean. This 2020 map documents a topography of dramatic elevation changes and a complex shoreline characteristic of the Gulf of Alaska's volcanic island chains. Though uninhabited on this specific quadrangle, the terrain and coastal features provide critical context for the surrounding marine environment and the historical shifts in regional land use within the Aleutian archipelago. The grid lines of townships like t57s r76w and t58s r76w partition the land and sea, indicating the modern administrative structure of this remote Alaskan territory.
