1989 Map of Unimak A-4

USGS Topo · Published 1989

About this map

Tigalda Island and Avatanak Island dominate this maritime survey of the Fox Islands group in the late twentieth century. Located within the Aleutian Islands Wilderness, these landmasses are characterized by sharp coastal features such as Avatanak Point and sheltered waters like Kelp Bay and Tigalda Bay. The map records a landscape shaped by the meeting of the Bering Sea and the Pacific Ocean, separated by the Avatanak Strait and Derbin Strait. While there are no roads or trails indicated on the islands, the placement of smaller outcrops like Tanginak Island and Derbin Island provides a detailed view of the remote archipelago's geography as documented in the late 1980s.
