2020 Map of Unimak A-5 SE

USGS Topo · Published 2020

About this map

Avatanak Island and its surrounding Aleutian waters are the focal point of this 2020 topographic survey produced by the U.S. Geological Survey. The landscape is defined by its maritime geography, situated between the Avatanak Strait to the north and the open Pacific Ocean to the south. The island's eastern shoreline is marked by the indentation of Chimney Cove, while its northern coast is guarded by the prominent landmark of Basalt Rock. The map illustrates the island's isolation within the eastern Aleutians, showing the narrow passage of Rootok Strait to the west. This survey provides a precise record of coastal topography and elevations, capturing the natural features of this maritime environment in the Aleutians East Borough.
