1989 Map of Unimak B-5

USGS Topo · Published 1989

About this map

Akun Island dominates the southern reaches of this 1989 provisional survey, showcasing the maritime isolation of the eastern Aleutians. The topography centers on the heights of Mount Gilbert and the surrounding coastal prominences of Akun Head and Billings Head. As part of the Alaska Maritime National Wildlife Refuge, the area is characterized by dramatic inlets and coves where the Akutan Bay and Akun Bay meet the cold waters of the Bering Sea. This map is particularly useful for visualizing the untouched coastline of the Aleutians East Borough before modern satellite precision, reflecting the geographic data as it stood in the early 1980s. Key water features like Little Bay and the sheltered Helianthus Cove provide insight into the natural harbors and rugged shoreline that define this northern landscape.
