About this map

Tanaga Island dominates the eastern portion of this maritime survey, situated where the Bering Sea meets the northern Pacific Ocean. This remote volcanic landscape in the Aleutian Islands is characterized by dramatic coastal features like the jagged Kulak Point and the southwestern protrusion of Cape Amagalik. The map highlights the complex hydrography of the Andreanof Islands chain, detailing hazardous navigation points such as Inferno Reef and Scarab Rock.

Smaller landmasses like Whip Island and Tidgituk Island are documented alongside sheltered waters including Lash Bay and the expansive Tanaga Bay. The absence of roads or permanent settlements underscores the isolation of this environment, focusing instead on the precise topographical contours of the island and the named landmarks used by mariners and researchers to navigate these northern waters.
