1989 Map of Unalaska D-2

USGS Topo · Published 1989

About this map

Bering Sea waters dominate this late-twentieth-century maritime survey, focusing on the northern entrance to one of the most vital natural harbors in the Aleutian chain. The chart highlights the approach to Unalaska Bay along the rugged northern coast of Unalaska Island. Key navigational aids and landforms for mariners include the Priest Rock Light and the prominent headland at Cape Kalekta, which anchors the eastern edge of the bay entrance. While most of the map area covers open ocean, the terrestrial portions reveal the complex shoreline of the Unalaska Island coastline, including the distinctively named coastal feature The Dry Dock. This provisional map, compiled from 1983 aerial photography, captures the remote character of the island’s northern reaches before later modern development or coastal changes altered these historic landmarks.
