1954 Map of Trinity Islands

USGS Topo · Published 1978

About this map

Tugidak Island and Sitkinak Island anchor this coastal survey of the southern Kodiak archipelago. The map reveals a maritime landscape defined by tidal flats and treacherous passages, with the isolated Chirikof Island shown in a detailed inset. On Sitkinak, the prominent Sitkinak Dome rises above Manila Lake, while coastal features like Russian Harbor and Whirlpool Pt reflect the area's navigational history. The northern reaches of the map detail the Aliulik Peninsula and the complex shoreline of Alitak Bay, including Sukhoi Lagoon and Kempff Bay. Small markers for Cabins and a Radio Tower provide rare evidence of human habitation in this maritime environment. This 1950s data, compiled from earlier hydrographic charts and aerial photography, captures the precise contours of the Trinity Islands before significant modern shifts in coastal geomorphology.
