The pyramid is a new archeological discovery.
The great thing about this trip was that it was only within an hour drive from San Miguel de Allende. I loved it. The archeological site was found in 1984. It was recently opened to the public. Some excavation has been complete but much work has been completed. The people from this site where the Otomi tribe. Browse through the slideshow and movie clip(s). I will try to get some links set up to it as well.
