2020 Map of Stepovak Bay D-4 SE

USGS Topo · Published 2020

About this map

Chiachi Island dominates this maritime survey, rising sharply from the waters of the Gulf of Alaska. The island’s complex shoreline and steep topography create the sheltered anchorage of Chiachi Bay, a significant natural feature for navigation in this remote archipelago. Surrounding the main island are several smaller landforms, including the distinctively named Pinnacle Rock and Pinusuk Island to the east. This 2020 map, based on data from the U.S. Geological Survey and the Alaska Department of Transportation, provides a high-resolution look at the coastline as it exists in the 21st century. The landscape is characterized by its isolation, with no roads or permanent settlements indicated, focusing entirely on the natural hydrography and terrain of the Chiachi Islands and nearby Petrel Island.
