The ancient Mayan civilization collapsed due to a century-long drought, new research suggests.

Minerals taken from Belize's famous underwater cave, known as the Blue Hole, as well as lagoons nearby, show that an extreme drought occurred between A.D. 800 and A.D. 900, right when the Mayan civilization disintegrated. After the rains returned, the Mayans moved north — but they disappeared again a few centuries later, and that disappearance occurred at the same time as another dry spell, the sediments reveal. 

Although the findings aren't the first to tie a drought to the Mayan culture's demise, the new results strengthen the case that dry periods were indeed the culprit. That's because the data come from several spots in a region central to the Mayan heartland, said study co-author André Droxler, an Earth scientist at Rice University.
