About this map

The Gulf of Alaska dominates this maritime survey, covering the vast majority of the nautical expanse within the Prince of Wales-Hyder census area. Located at the extreme southern edge of the Alaskan panhandle, this map focuses almost entirely on open water, serving as a clean record of the sea lanes and maritime boundaries near the international border. The absence of landmass or terrestrial landmarks highlights the navigational character of this specific sector, where the Pacific Ocean meets the complex coastline of the Alexander Archipelago. It represents a vital reference for the hydrology and bathymetry of the northern Pacific waters, illustrating the maritime environment as it was recorded by the U.S. Geological Survey in the late 2010s.
