2021 Map of Rat Islands C-1 NW

USGS Topo · Published 2021

About this map

Semisopochnoi Island, part of the volcanic Rat Islands chain in the Aleutian Islands, presents a complex coastal and mountain landscape. The western portion of the map is dominated by the steep elevations of Perret Ridge and the peak of Ragged Top, reflecting the island's active tectonic origins. The coastline is deeply defined by a series of named maritime landmarks, including the East-northeast Indent and the sheltered East-southeast Bight. Strategic maritime points such as Pochnoi Point and East-southeast Head serve as primary identifiers for the island's profile against the Bering Sea. This modern survey provides precise contouring of these uninhabited landforms, illustrating the extreme isolation and volcanic geography typical of the western Aleutian chain.
