Another ritual behaved toward sacred merging of the object deity Sun with Great Goddess-Mother, personified as a the rocky mountain peak and was performed in the middle of summer (July 30 or 31). On that day, the rays of the morning sun, which emerged behind the ritual marker on the highest part of the site going down trough artificially cut rock, twenty feet below the marker and enlighten only one of the participants in the ceremony, which sat on one of several stone seats on lower western platform location. Both rituals were designed to ensure greater fertility and cyclical renewal of nature.
