This image of a bird was incised in wet mud banks deep inside Mud Glyph Cave in Tennessee. Mud, which is associated with the origin of the world by many Southeast native American peoples, was often used as a medium by prehistoric cave artists.
Giant Wheels The area near the Azraq Oasis in Jordan has hundreds of wheels, large structures made of stone that date back at least 2,000 years. These wheel structures are often found on lava fields and range from 82 feet to 230 feet (25 meters to 70 meters) across. Archaeologists used to believe that the Azraq Oasis wheels were used as a cemetery although that is now in doubt.
