Great Riddles in Archaeology Lecture Series at the Penn Museum Noah's Ark One of the bestknown Bible stories is that of Noah's ark and the world-engulfing flood. Dr. Fredrik Hiebert, National Geographic Explorer, was part of a team that discovered evidence of man-made structures 300 feet below the surface of the Black Sea, adding credence to theories that this was the location of the flood that inspired the biblical and Babylonian stories. Dr. Hiebert discusses his discoveries and other evidence helping to shed light on the mystery of Noah's ark.
