1989 Map of Unalaska B-2

About this map

Unalaska Island is defined here by its complex eastern coastline, where the land fragmentizes into numerous deep-water inlets and narrow peninsulas. The interior terrain rises sharply from the Pacific Ocean, creating a landscape dominated by drainage patterns like Amugul Cr and protected maritime corridors. In the late 1980s, these waterways provided the primary means of navigating this part of the Aleutians, as evidenced by the lack of overland infrastructure between Staraya Bay and the southern reaches of Three Island Bay. Maritime landmarks such as Cape Yanaliuk and Kayak Cape anchor the coastal geography, while smaller features like Three Islands and Erskine Bay emphasize the intricate relationship between the land and the Beaver Inlet. This provisional survey represents the region's topography before more modern digital updates, capturing the wilderness character of the islands.
