1962 Map of Harrison Bay C-1

About this map

Thetis Island sits as a lonely marker along the northern Alaskan coast in this mid-century maritime survey. The Beaufort Sea dominates the upper portion of the sheet, where soundings in fathoms reveal the shallow, shifting nature of the arctic shelf. To the south, the waters of Harrison Bay stretch toward the mainland, characterized by tidal flats and mud-sand compositions. Compiled from photogrammetric methods and coastal hydrography by the Army Map Service, this map serves as a precise technical study of an area where the boundary between sea and tundra is constantly redefined by ice and tide. The lack of terrestrial settlements emphasizes the isolation of this North Slope environment, where the primary features are the submerged hazards and bathymetric contours essential for coastal navigation.
