Prince William Sound dominates this coastal survey, represented as a vast expanse of open water within the Valdez-Cordova Census Area. Unlike many terrestrial quadrangles, this map focuses almost entirely on the hydrography of the sound, providing a specialized look at the maritime geography of the Unorganized Borough. Compiled from data sources such as the National Hydrography Dataset, the sheet emphasizes the marine environment of this specific Alaskan corridor. Because the map contains no landmasses, it serves as a clean record of the sound's positioning and extent at the time of the 2018 revision.
