NOVA joins four scientists in their global pursuit of clues to a
massive volcanic eruption that appears to have had a devastating
impact on the Earth 75,000 years ago. And if they're right, the
ancient supervolcano -- and others like it -- may someday reawaken,
with catastrophic consequences for our modern world. Now, an array of
clues -- scattered ashes and ice cores, tiny ocean creatures and
steaming lakeside rocks -- are brought together to solve the "Mystery
of the Megavolcano."

Here's what you'll find on the companion Web site:
