Long ago, the Mayan civilization collapsed, unceremoniously leaving behind a lot of mysteries as to what happened. One of those mysteries has to do with the reason they suddenly “disappeared” from the Earth. We know they migrated north around A.D. 800, and one prevailing theory has been that their migration was due to drought. New findings bolster that theory, with scientists taking minerals from an underwater cave to better discover what really happened to the Mayans. The drought may have actually been worse than imagined.
Minerals pinched from an underwater cave in Belize known as the Blue Hole show a significant drought occurred between A.D. 800 and A.D. 900. That’s roughly the same time we know the Mayan civilization to have collapsed.
