Amazing stuff. The Mayans were amazing. I wish Archaelogists weren't so much neat freaks though. They should just take their whip and walk in there. What are you going to destroy, really? I don't want to be dead by the time they fully excavate it.
It seems there are new discoveries in Meso American arch. on almost a weekly basis. We've now pushed back the Mayan civilization by several centuries, the Peruvian by a couple thousand and there is just a small piece of the whole being excavated at this point.
