2020 Map of False Pass C-4 NW
USGS Topo · Published 2020About this map
Unimak Island serves as the focal point for this 2020 survey, where the terrestrial elevations of the Aleutian Islands meet the open waters of the Pacific Ocean. The geography is defined by prominent coastal summits including Ikatok Peak and Dora Peak, which overlook the southern reach of the Ikatan Peninsula. Along the jagged shoreline, the sheltered waters of Bora Harbor and Dora Harbor provide distinct maritime landmarks in an otherwise exposed coastal environment. South of the main island landmass, the isolated form of Bird Island rises from the sea, illustrating the fragmented volcanic nature of this remote archipelago. The topography is marked by steep relief and complex drainage patterns, reflecting the active geological processes inherent to this subarctic chain.
