Teotihuacan
From Indiana Jones Wiki
Teotihuacan is a historical region located in central Mexico, noted for its large number of pre-Columbian pyramids. In 1947, Indiana Jones was studying the famous Pyramid of the Sun and discovered Teotihuacan's lost Olmec Valley, an uncharted and unpopulated region that was the secret location of Azerim's piece of the Infernal Machine.
