Yaxha is a lesser known complex of Mayan ruins....much of which is not yet excavated. One of the pyramids of this twin complex is partially excavated while the second is not at all. The photo of the accompanying sign gives an idea of what the complex would look like if it were excavated.
The Wikipedia article for twin pyraimids (

"Yaxha Plaza A is a twin-pyramid complex located immediately north of its East Acropolis. A sculpted stela was erected at the base of the West Pyramid of the complex; Stela 13 was sculpted but has been broken into fragments, although much of the sculpture is preserved. The text on the stela includes a date in 793, the latest recorded date at the city. Stela 13 bears the image of a king of Yaxha together with a text describing the celebration of an equinox."
