Scientists know all about the sophisticated calendars and writing system of the Maya, as well as their ritual sacrifices. But as for exactly what caused the the ancient civilization to collapse around 900 A.D., that’s long been a bit of a mystery.

The researchers analyzed sediment samples from the Blue Hole, looking specifically at variations in color, grain size, and layer thickness. They also examined samples from the Belize Central Shelf Lagoon, a body of water attached to the mainland, noting differences in the samples’ ratio of titanium to aluminum, which helps provide an estimate for rainfall levels.

The analyses revealed low levels of precipitation and a drop in the frequency of tropical cyclones from 800 to 900 A.D. in the Yucatan peninsula–which —> Read More Here
