1951 Map of Trinity Islands

USGS Topo · Published 1951

About this map

Kodiak Island and its southwestern reaches are documented here during the early 1950s, a period when this maritime landscape was defined by remote outposts and the fishing industry. The map illustrates the specialized infrastructure of the era, including a Cannery and a Light marking the approach to Alitak Bay. Settlements like Akhiok and Alitak anchor the eastern shoreline, while the vast Kodiak National Wildlife Refuge encompasses much of the interior. Further offshore, the Trinity Islands consist of Tugidak Island and Sitkinak Island, characterized by unique features such as Sitkinak Lagoon and the high point of Sitkinak Dome. An inset map focuses on the isolated Chirikof Island to the southwest, noting local maritime landmarks like Nagai Rocks and Southwest Anchorage, which served the few vessels navigating these open waters of the Pacific Ocean.
