2021 Map of Unimak A-3 NW

About this map

Kaligagan Island stands as a lonely landmass in the waters of the Pacific Ocean, defined by its isolation within the Aleutian archipelago. This nautical landscape is segmented by the Ugamak Strait, a critical passage for local navigation between islands. To the south, the shoreline is punctuated by Tigalda Bay and the coastal rise of Unimguukux, showing the complex relationship between the sea and the volcanic terrain of the Aleutians East Borough. The lack of inland infrastructure emphasizes the maritime-dependent nature of this region, where survival and movement are dictated entirely by the surrounding tides and sheltered inlets like Tigalda Bay.
