2021 Map of Trinity Islands C-1 SE

About this map

Sitkinak Island dominates this maritime study, showcasing a remote Alaskan landscape defined by the shifting boundaries of land and sea. On the northern coast, the hazardous waters of Whirlpool Shoals and Whirlpool Point indicate a dynamic coastal environment where powerful currents meet the island's edge. The interior is marked by significant elevation changes, punctuated by Mark Lake, which sits tucked within the western hills. Along the eastern shore, the sheltered waters of Sitkinak Lagoon provide a stark contrast to the open expanse of the Gulf of Alaska to the south. This 2021 survey documents the topography of the island's southern and central reaches, detailing the complex drainage patterns and coastal features essential for maritime navigation and land management within the Kodiak Island Borough.
