Too cool that something this big can be hidden for so long.

Archeologists working deep in the Mexican jungle say they have discovered
a large Mayan city, complete with many monuments and carvings.

The city was found in Campeche, an area in southeastern Mexico that is
home to dozens of Mayan sites, including the ancient city of Calakmul, a
UNESCO World Heritage site.

Dubbed Chactún, “Red Stone,” or “Piedra Grande,” the newest find spans
close to 54 acres and may have been a governmental seat between 600
and 900 A.D., Spanish international news agency EFE reports.
