- echelon 4y agoThe article on the lake itself [1] seems to paint a different picture - contradictory evidence and a lack of certainty. While the recent 2017 study cites core samples, earlier studies suggested that sediments were not a part of the lake formation. I don't think there's enough detail in the Wikipedia articles to really shed light on this. Every study seems to reach different conclusions.
