1954 Map of Trinity Islands

USGS Topo · Published 1970

About this map

Kodiak Island and its southwestern maritime reaches define this mid-century coastal study, centered on the Trinity Islands and the remote Chirikof Island. The settlement of Akhiok stands as a focal point near Alitak Bay, surrounded by a complex network of coastal features including Sukhoi Lagoon, Deadman Bay, and Moser Bay. The terrain transitions from the elevations of Tungulara Mountain and Sitkinak Dome to the expansive Tidal Flat of Tugidak Island. Evidence of seasonal or specialized activity is seen in the scattered cabins along the shores of Sitkinak Island and the isolated Cabin on Chirikof Island. This map captures the maritime infrastructure and coastal geography prior to major modern developments, documenting navigational hazards like Alitak Shoal, Nelson Reef, and Middle Reef alongside sheltered locations such as Russian Harbor and Southwest Anchorage.
