The late investigator and cryptozoologist Ivan T. Sanderson concluded that underwater UFOs were real and operated by undersea inhabitants, said Sauder, who added that Lake Erie is a hotspot for such activity.

A remarkable UFO sighing over Lake Erie was reported last year when a resident of Huron, Ohio captured a strange large cone shaped metal looking object with two triangular bright lights came out of it over Lake Erie before it all disappeared.

There are underground salt deposits in the lake area, which are easier to drill into and create caverns than regular rock, he explained. Intriguingly, he also suggested that the underground bases may be connected with time travel, as water has many unusual properties and it may somehow facilitate the malleability of time.
