The canal system was discovered with sonars. One of the water canals discovered beneath the Temple of the Inscriptions at the archaeological site of Palenque, in the state of Chiapas. Water was still running through the main canal when it was discovered, suggesting that its source is a natural spring. Gonzalez did not rule out the possibility that the canals were part of a drainage or water supply system. "The presence of these canals is very important and very significant," said Arnoldo Gonzalez, the directory of archeology in Palenque.
