“Don’t tell Indiana Jones, but most archaeologists pack spades, not bullwhips, and big discoveries usually come after lots of digging, not looting. Maya discoveries in Mexico that are rewriting the history of this classic civilization, for example, are coming from years of careful digging, not looted idols.

The classic Maya were part of a Central American civilization best known for stepped pyramids, beautiful carvings and murals and the widespread abandonment of cities around 900 A.D. in southern Mexico, Guatemala, Belize and El Salvador, leaving the Maya only the northern lowlands of the Yucatan peninsula. The conventional wisdom of this upheaval is that many Maya moved north at the time of this collapse, also colonizing the hilly “Puuc” region of the Yucatan for a short while, until those new cities collapsed as well.

But that story of the Maya is wrong, suggests archaeologist George Bey of Millsaps College in Jackson, Miss., who is co-leading an investigation of the abandoned city of Kiuic with Mexican archaeologist Tomas Gallareta of Mexico’s National Institute of Archaeology and History. “Our work indicates that instead the Puuc region was occupied for almost 2,000 years before the collapse in the south,” says Bey, by e-mail.”
