We stopped by here while traveling through Jalisco. I hadn't realized prior to my travels that there were so many archaeological sites in this area. This particular site goes back possibly as far as 300 BC. The most notable feature of this site is the pictured 60 foot high circular stepped pyramid structure. It was originally topped by a pole and was used for ceremonies honoring the wind god. There were originally a few of these structures. They were surrounded by rectangular mounds in circle around each pyramid. In addition to be an interesting education/insight into this ancient culture, it was also a beautiful spot.
