About this map

Great Sitkin Island and Ulak Island emerge from the Bering Sea in this 2021 topographic record of the Andreanof Islands. Located within the larger Aleutian Islands chain, this chart details the northern coastline of Great Sitkin, specifically the prominent landform at Bugle Point. The marine geography is defined by coastal features such as Yoke Bay and the waterway of Iliqiis.

This modern survey by the U.S. Geological Survey focuses on these isolated volcanic landmasses where the landscape is dominated by elevation contours rather than human infrastructure. The inclusion of the Public Land Survey System grid, including t94s r190w, provides a formal administrative overlay for these remote Aleutian territories, useful for documenting precise locations in a region primarily shaped by geological and maritime forces.
