2021 Map of Attu A-1 NW

USGS Topo · Published 2021

About this map

Agattu Island presents a profile of the remote western Aleutians, where the terrain rises sharply from the Bering Sea into the heights of Cone Peak. The island's northern coastline is punctuated by notable geological features, from the dramatic Monolith Point to the sheltered waters of McDonald Cove. Inland, the topographic detail traces the deep carving of Triton Valley, illustrating the glacial or volcanic forces that shaped this isolated archipelago. This modern survey by the U.S. Geological Survey provides a clear view of the island's marine approaches, including Agattu Roadstead and Aga Cove, areas traditionally significant for navigation in these treacherous northern waters. The absence of roads or permanent structures on this sheet underscores the uninhabited and natural state of the island in the early twenty-first century.
