From the evidence that supports this theory, there is a 3 meter wide channel that surrounds the base of the pyramid, which is related to the meaning of Altepetl or hill of water. As well as the existence of children's burials offered as an offering to the god of water, in the four corners of the pyramidal base. In addition to the mural paintings in Tepantitla and the detailed engravings of Tláloc in the Palace of Quetzalcóatl.
