1963 Map of False Pass D-0

USGS Topo · Published 1967

About this map

Outer Iliasik Island and a scattering of smaller volcanic outcroppings define this maritime landscape in the Aleutians East during the early 1960s. Surveyed primarily through photogrammetric methods from 1957 aerial photography and field-annotated in 1963, the sheet emphasizes the treacherous hydrography of the Pacific Ocean surrounding these remote landmasses. The map details an intricate network of submerged hazards, most notably the expansive Sandman Reefs and isolated maritime landmarks like Pinnacle Rock and John Rock. These features are vital for understanding the historical navigation routes and maritime safety of the era, as the U.S. Geological Survey incorporated bathymetric data from mid-century Coast and Geodetic Survey charts to illustrate the relationship between the rugged islets like Sarana Island and the shallow shelf of the Bering Sea approaches.
