Hidden rain forest Maya lost city of Holtun – FOUND!

Three-dimensional mapping has “erased” centuries of jungle growth, revealing the rough contours of nearly a hundred buildings, according to research presented earlier this month.

Though it’s long been known to locals that something—something big—is buried in this patch of Guatemalan rain forest, it’s only now that archaeologists are able to begin teasing out what exactly Head of Stone was.

Using GPS and electronic distance-measurement technology last year, the researchers plotted the locations and elevations of a seven-story-tall pyramid, an astronomical observatory, a ritual ball court, several stone residences, and other structures.
