Caption: Northeast Corner Inset
Additional Description: Notice drill marks in two large stones on this corner. These stones show the drilled holes where they were split from solid bedrock. A line of holes was drilled and chisels and wedges were driven into them. The chisels were hammered in sequence until the stone split off. These stones were placed upside down from their original position in the bedrock.
