CARACOL:

The Caracol: A great religious site at Chichén Itzá, a post-classic Maya site. To the left are
purification baths, with one round kiva shaped pool. The doorway has an imprint of "the red hand
of creation". The tower was created for complex astronomical observation. Sculpted heads on the
surrounding walls had "holes in the tops of their heads"; in the Hopi way this reminds us of an
ancient teaching to "keep this opening clear to communicate with the Creator".
