1989 Map of Unalaska A-2

USGS Topo · Published 1989

About this map

Pacific Ocean waters dominate this late-twentieth-century maritime survey, which focuses on a coastal segment of the Aleutian chain. The map captures a rugged southwestern portion of Unalaska Island, defined primarily by its dramatic interface with the sea. At the island's edge, Whalebone Cape stands as a prominent navigational landmark, marking the transition from the open ocean to the island's rocky periphery. Compiled from 1983 photography, this provisional edition illustrates the stark, unpopulated nature of this subarctic environment during the 1980s. The absence of roads or settlements emphasizes the isolation of the terrain, where the topography is dictated by steep coastal elevations and the unrelenting influence of the surrounding sea.
