2021 Map of Rat Islands A-3 SE
USGS Topo · Published 2021About this map
Saint Makarius Point and Grampus Point define the southern shoreline of this remote Aleutian landscape, where the volcanic island terrain meets the Bering Sea. This modern survey reveals a specialized corner of the Rat Islands, highlighting coastal features such as Tanasux and the eastern extension toward Pillow Point. The map is largely dominated by open water and maritime boundaries, reflecting the isolation of these islands. The terrestrial portions are marked by steep contour intervals that illustrate the sharp rise from the sea to the interior ridges, a characteristic pattern for this volcanic chain. Researchers studying Aleutian geography will find the precise location of named points and the surrounding bathymetric context useful for understanding the navigational hazards and landforms of the western census area.
