2020 Map of Unimak A-4 SE

USGS Topo · Published 2020

About this map

Tigalda Island dominates this maritime survey, showcasing the dramatic topography of the Krenitzin Islands within the broader Aleutian Islands chain. The map details a complex shoreline where the Pacific Ocean meets deep indentations such as Kelp Bay and Welcome Bay on the northern coast, and the protected waters of Derbin Bay to the south. Small landforms like Derbin Island and the specifically named point of Qatunaalux emphasize the importance of coastal navigation in this isolated archipelago. This modern elevation study captures the area's volcanic character through dense contouring, illustrating how the Fox Islands landscape remains defined by its steep peaks and remote island geometry, largely untouched by industrial development.
