About this map

Port O'Brien sits along the western coast of Kodiak Island, positioned where the Northeast Arm Uganik Bay meets the main waters of Uganik Bay. This 2021 survey illustrates a landscape dominated by deep glacial fjords and high elevations, with Sheep Island providing a prominent landform within the bay's entrance. The interior geography is defined by the drainage systems of Uganik Lake and the Uganik River, which flow through the southwestern portion of the quadrangle.

To the east, the map tracks the headwaters and coastal reach of Terror Bay and the Terror River. The topographic detail provided by the U.S. Geological Survey captures the intricate network of wetlands and the steep gradients that characterize this part of the island. This documentation serves as a contemporary record of the remote coastal settlements and hydrological patterns that define the region's wilderness and limited infrastructure.
