Researchers through a study discovered evidence for an extreme drought between 800 and 900 AD, a similar time period when the ancient Maya civilization collapsed. For the study, the researchers examined minerals from the famous underwater cave in Belize, known as Blue Hole.
The research indicated that the drought played a major role in the destruction of the Maya. The Maya culture extended through much of what is now southern Mexico, Belize, Honduras, El Salvador, and Guatemala. The culture existed for more than 2,000 years.
