Alaska’s coastal waters have long been linked to Unidentified Submerged Objects (USOs), with Whittier and the surrounding Prince William Sound emerging as focal points. A 1969 account from a former Naval Communications Officer describes a submerged craft near Whittier that allegedly disrupted sonar and communications. More recently, the Discovery series The Alaska Triangle featured claims of underwater bases, citing radar anomalies and sightings of craft entering and exiting the water. The region’s deep fjords and limited human access make it a plausible candidate for covert activity. The area is frequently mentioned in cryptid and UFO forums, often linked to broader Alaska Triangle phenomena.
