USGS Topo · Published 2021About this map
Umnak Island, situated within the Fox Islands chain of the Aleutian Islands, presents a sparsely populated coastal landscape shaped by volcanic activity and the surrounding Pacific Ocean. This 2021 survey details the island's northwestern reaches, where the coastline is defined by sharp geographical markers such as Thumb Point and the offshore formations known as The Pillars. The presence of Partov Cove suggests a natural harbor along an otherwise exposed shoreline.
