About this map

The Andreanof Islands within the larger Aleutian Islands chain define the northern maritime boundaries of this survey. The landscape is dominated by the southern coastal extensions of these volcanic islands as they meet the Pacific Ocean. Key coastal features include the prominent Ragged Point and the sheltered waters of Quail Bay. To the east, the map captures the entrance to Little Tanaga Strait, a critical passage for maritime navigation in these subarctic waters. The map is largely a study of bathymetry and coastline where the Bering Sea influences meet the open ocean, reflecting the isolated and maritime-dependent nature of this region of Alaska.
