2021 Map of Amukta C-3 NE

USGS Topo · Published 2021

About this map

Yunaska Island dominates this portion of the Islands of Four Mountains in the Aleutian Islands chain. This volcanic landscape is defined by its steep coastal contours meeting the cold waters of the Bering Sea. On the western shore of the island, Crater Anchorage provides a natural seafaring reference point along a coast otherwise dominated by high ridges and sharp elevation changes. The map documents the topographical character of this remote archipelago, tracing the land's rise from the shoreline into the interior peaks. The absence of human-made infrastructure emphasizes the isolation of this island group, where the terrain is governed by the geological forces of the Aleutian arc.
