Episode 6A - "Cracking the Code": During a storm, while Pepper and Tomas are aboard the Mimi having dinner, the anchor comes loose, causing them to drift towards the reef. The next day, the rest of the group returns to the Mimi to begin mapping out exploring for Mayan artifacts along the ocean floor. Above water, Quiche teaches C.T. how to write numbers in Mayan. In turn, C.T. creates a computer program which generates the Mayan number when you type in a regular number. Over dinner, they re-examine the pot which they thought was a fake, but which actually may be an ancient artifact. They decide to travel to the archaeology labs at Enoch to see if they can find out more. Expedition 6B - "Written in Stone": Hosted by Carla Douglin and Ben Affleck. Together they visit Copan, one the greatest Mayan cities, which is located 200 miles South from Palanque and Talum, in Honduras. There they meet with a college student and archaeologists who decipher ancient Mayan emblem glyphs and are reconstructing some of the ruins located there.
