The title and article are a little sensationalized. I grew up in Guatemala, and the entire Yucatan peninsula, along with Guatemala, Belize and Honduras, are covered in "undiscovered" cities. I'd regularly dig up pottery and carved stones in fields and garden beds. The Calakmul area is especially dense in ruins. Most xateros (rubber tappers) know them all and can guide you to them for a couple bucks. Very few of them are surveyed or even mentioned in literature.
