Question: where are the olmec colossal heads located?
Answer: The La Cobata head was found on El Vigia hill in the Sierra de los Tuxtlas and the stone from Tres Zapotes Colossal Head 1 and Nestepe Colossal Head 1 (also known as Tres Zapotes Monuments A and Q) came from the same hill. The boulders were transported over 150 kilometres (93 mi) from the source of the stone.
