1954 Map of Trinity Islands

USGS Topo · Published 1956

About this map

Kodiak Island and its southern outliers are documented in this mid-century maritime study, emphasizing the complex coastline of the Trinity Islands. The settlement of Akhiok stands as a focal point near Alitak Bay, while the expansive Tugidak Island and Sitkinak Island dominate the southern waters. Topographic details like Sitkinak Dome and Tungulara Mountain provide landmark elevations for navigators, complemented by numerous coastal features such as Sukhoi Lagoon and Russian Harbor. The map's inclusion of Chirikof Island as a detailed inset highlights its remote position in the Pacific Ocean, far south of the primary island chain. This survey captures a moment of active maritime geography, noting features such as Tugidak Passage and the dangerous Breakers that influenced navigation through the Sitkinak Strait.
