In a building sometimes called the Group of the Mortars we find two precise carved circular "mortars." However, their size (about one-half meter in diameter) and permanent location make this use unlikely. This photograph was made after a rainstorm. The concave shapes were filled with water and the sky was refected as from a mirror. Do these stones have an astronomical connection? --- probably not --- one more mystery.
We leave the city with a few images that do not fit in a sequence.
