Rafael Cobos Palma, general coordinator of archaeology at Chichen Itza and leader of the “Grand Leveling” project has been digging throughout Chichén Itzá to determine how the ancient city evolved.

Currently a multi-disciplinary team from INAH, the federal agency in charge of Mexico’s ruins, and Universidad Autónoma de Yucatán, a university in Merida, are studying the data from the digging which began in February, 2010. Furthermore, the pits will likely never be filled, given the “didactic and academic importance” of the substructures that have been exposed, and how they demonstrate the importance of Chichen Itza as a Maya cosmopolitan city.
