The Lore

Iliamna Lake in Alaska is the state's largest freshwater body, and for centuries the Dena'ina people have warned of large creatures in its waters. Modern pilots have reported seeing enormous dark shapes moving below the surface, estimated at 10-30 feet long. In 1979, the Anchorage Daily News offered a reward for proof. Proposed explanations include unusually large white sturgeon or sleeper sharks that may have entered through river systems.
