About this map

Seguam Island and the eastern reach of the Andreanof Islands define this survey of the central Aleutians. The topography is dominated by the volcanic profile of Pyre Peak, surrounded by coastal landmarks such as Wharf Point, Moundhill Point, and Lava Point. These features, along with the deep indentations of Finch Cove and Lava Cove, reflect a landscape shaped by geothermal activity and North Pacific weathering.

To the west, the long silhouette of Amlia Island stretches across the Bering Sea and Pacific Ocean boundary. Coastal navigators of the era would recognize the critical maritime passes of Seguam Pass and Amukta Pass, as well as safe havens like Svechnikof Harbor. Smaller landmasses including Agligadak Island and Sagigik Island dot the southern coastline, illustrating the fragmented nature of this volcanic archipelago.
