1951 Map of Seguam

USGS Topo · Published 1952

About this map

Seguam Island and the eastern extent of the Andreanof Islands dominate this 1951 reconnaissance of the Aleutians. The volcanic character of the landscape is evident through landmarks such as Pyre Peak and the naming of Lava Point and Lava Cove. The map details the remote coastal geography of Am Lia Island, tracing a rugged shoreline from Cape Misty to the narrow Agligadak Reefs at its eastern tip. Compiled from surveys dating back to 1933, the chart captures the navigational hazards of Seguam Pass and Amukta Pass, vital maritime corridors between the Bering Sea and the Pacific Ocean. This survey preserves the exact coastal nomenclature used by the U.S. Coast and Geodetic Survey before the mid-century, including isolated anchorages like Smeatonikof Harbor and distinctive landmarks like Haystack Rock.
