June 29 - Earthfiles recently had an interesting interview with Peter Lindberg, from the Ocean X team. Spoken about, was what they have found regarding the Baltic sea structure anomaly:
 

“The divers were swimming slowly over the large circular object
and suddenly passed over a ring of stones, like a small
Stone Age fireplace, on the right side.”
