Okay, this is just plain false. The Classical Maya collapse could be compared to the Fall of Rome or the end of the Han dynasty (although perhaps I should use Tang instead for historical proximity). That is to say, the Maya didn't disappear. Completely the opposite--the Classical Maya collapse is actually reflected in the rise of the Yucatec and other lowland Mayan city centers, notably Chichen Itza, which would itself decline a few hundred years later, before the city of Mayapan rose to prominence, again declining again a hundred-ish years later. Mayan city states remained independent and following Mayan cultural and religious practices even after the Spanish conquest of the Aztecs, with the last Mayan kingdom falling only in 1697. Even then, while no longer independent, Mayan culture still persists to this day.
There are civilizations that are hard to trace. What happened to the people of, say, Cahokia or Teotihuacan are still a mystery to this day. But the Maya are absolutely not one of those.
