2021 Map of Umnak A-6 SE

About this map

Uliaga Island stands at the center of this 2021 topographic survey, rising dramatically from the waters of the Bering Sea. Located within the larger chain of the Aleutian Islands, this map focuses on the easternmost portion of the Islands of Four Mountains. The southern portion of the sheet reveals the northern coast of Kagamil Island, separated from its northern neighbor by the waters of Uliaga Pass. These volcanic landmasses are defined by steep contour intervals that reach prominent peaks, with coastal landmarks such as Candlestick Point and North Cove providing the only breaks in the land-sea interface. The map illustrates the extreme isolation and volcanic geography of this part of Alaska, where the lack of human infrastructure or roads emphasizes the primitive state of the subarctic environment in the early 21st century.
