Fifty miles north of Mazatlan in Sinaloa State, north west Mexico, there is a beach known as Las Labradas where the rocks are covered in over 600 petroglyphs. Now Mexican investigators have uncovered archaeological sites in the vicinity dating to the Archaic period (2500-1000 BCE) along with another later site that may provide clues to the creators of the Las Labradas petroglyphs.
