2021 Map of Trinity Islands C-2 SW

About this map

Tugidak Island, part of the Trinity Islands archipelago, dominates this coastal survey along the southwestern edge of the Kodiak Island Borough. The landscape is a complex network of wetlands and small water bodies that characterize the interior of the island, bounded to the north and east by the Gulf of Alaska. The survey illustrates a terrain defined by low elevations and intricate hydrology, with numerous small ponds scattered across the southern portion of the island. This 2021 data from the U.S. Geological Survey provides a clear view of the island's natural state, showing the shoreline as it transitions into the open gulf without any mapped settlements or permanent road infrastructure.
