The Circular Pyramids of Guachimontones

In the beginnings of their 16,000-mile honeymoon adventure, California natives Dana and Ginger Lamb made it to the state of Jalisco in western Mexico.  The year was 1933.  A little over an hour west of Guadalajara was the sleepy town of Teuchitlán.  The two knew they were in a special place.  The town’s name was a Spanish corruption of the native name for the place Teotzitlán, which means, in the Nahuatl language of the Aztecs, “the place dedicated to divine forces,” or “where the gods are revered.”  Just outside of town was a vast low-lying ruined city, overgrown with brush and trees.  The Lambs had heard of this place, first described to the outside world in an obscure publication by British traveler Adela Breton in the 1890s, but no one knew very much about it.  Locals would come and take the stones away for building in town or for other uses in the country.  They called this area Guachimontones which combines two words, “guachis,” a native word for a type of small willowy tree and “montones,” which means “a lot” in Spanish.  The Lambs were so fascinated by this little-known place that they mentioned it in their 1938 book titled Enchanted Vagabonds which was one of the most-read non-fiction books in their day.  Dana and Ginger Lamb continued on their honeymoon adventure and Guachimontones remained a mere footnote in travelogues and tourist brochures until the early 1970s when more outside attention was drawn to the site, especially the city’s most curious features, the circular pyramids dominating the city found nowhere else in the world.

Archaeologists initially believed that Guachimontones was an Aztec outpost or perhaps belonged to an early Tarascan kingdom.  As excavations began in earnest in the 1970s, Guachimontones distinguished itself as being part of a previously unknown culture soon dubbed “The Teuchitlán Tradition.”  The people who occupied the city and surrounding areas have loosely been linked to similar civilizations more to the west, in the present-day Mexican state of Nayarit.  The people to the west also had circular buildings and plazas and shared some of the same ceramic traditions, as well as a custom of burying the dead in shaft tombs, but Guachimontones stands out because it is the home of circular stepped pyramids which are unknown in other parts of Mesoamerica and are perhaps unique in the world.   Archaeologist are still trying to put together the formal story of the Teuchitlán Tradition, but over the past 20 years much has been learned about the lost city of the strange round pyramids and the society that built it.

Occupation at the site of Guachimontones began around 350 BC and may have lasted until about 400 AD.  Archaeologists believe that the western Mexican Teuchitlán Tradition lasted from about 400 BC to around 900 AD, and may have declined about the time when Tarascan kingdoms began to influence the area from the east.  At its height, around 1,800 years ago, Guachimontones most likely had a population of around 40,000 which made it a very important civic-ceremonial site in the region.  15 smaller satellite towns in the area have been identified from the air, exhibiting the characteristic circular architecture found at Guachimontones.  Settlements from Guachimontones proper may have extended a full kilometer from the central part of the city, even going so far as Lake La Vega, where evidence of ancient chinampas, or floating gardens, has been found.  The main city of Guachimontones was dominated by monumental architecture primarily divided into individual circular complexes.  There are 10 such circular complexes following the same architectural “formula.”  Each complex has at its center a circular pyramid.   An elevated circular patio surrounds the pyramid.   A circular sidewalk surrounds the patio, and on this sidewalk there are between eight and twelve rectangular platforms.  Tombs exist under some of the platforms.  The stone platforms once had buildings on them made of perishable materials which may have served as residences of the elites or for ceremonial functions.  In the Teuchitlán Tradition there exists an overabundance of clay figurines which serve as a chronicle of daily life in the area in ancient times.  In some of these figurines, which were assembled into scenes, we can see the types of wooden and straw buildings with large roofs that may have surrounded the pyramids on the circular sidewalks.  In addition to the 10 circular complexes dominated by circular pyramids, at Guachimontones there are also four large rectangular plazas and two ball courts in which the ancient Mesoamerican ball game was played.  The ball court located between the two largest circular complexes is one of the largest such playing fields in all of western Mexico.  The biggest structure at the site is the circular pyramid found at what archaeologists call Circle Two.  It stands over 60 feet tall, with sweeping views of the surrounding terrain and of Lake La Vega, and includes 13 terraces leading up to a top altar with an additional 4 terraces.  The circular pyramids, and many of the other larger structures in the city were finished with lime and painted an orange-red, terra cotta color.  Many of the surfaces were decorated with geometrical designs or rudimentary pictographs.  There is no evidence that the ancient people of Guachimontones or the inhabitants of the other sites of the Teuchitlán Tradition had a written language.

The many unearthed figurines also give archaeologists some ideas about rituals practiced at Guachimontones.  A common figurine features the danza de cadenas or “chain dance,” a ritual dance still in practice in some parts of Mexico at the time of the Spanish Conquest.  The dance was usually comprised of all men or all women dancing as a group, arms interlocked and moving in a circular motion.  The centuries-old figurines depicting this dance are very reminiscent of the modern-day Mexican clay craft sold to tourists called “circle of friends.”  Some archaeologists believe that the danza de cadenas included hundreds of people locked in arms dancing in ritualistic fashion around the circular pyramids at Guachimontones.  Another ritual found in the figurines, and supported by the deep holes in the centers of each pyramid, was the voladores dance.  This dance is performed for thousands of tourists in Mexico today.  Performers climb to the top of a tall pole, tether themselves to the top of the pole and then jump, flying around the pole in a circular motion.  In the figurines, sometimes priests are depicted as laying on top of the pole with arms and legs outstretched to imitate a flying bird.  It’s clear that the flying rituals connected with the poles at the centers of the pyramids date back to the very early days of this city as excavations at the main pyramid at Guachimontones show a shaft for the voladores pole in each of the 4 layers of the pyramid in each of the 4 stages of its building.

The emphasis on the circular designs at Guachimontones has led some archaeologists and Mesoamerican cultural historians to believe that the site was a ritual center devoted to the ancient Mexican god of the wind known to the Aztecs as Ehecatl.  Although the Aztec Empire came to dominate Mexico about a thousand years after the demise of Guachimontones, many later beliefs throughout ancient Mexico have their foundations in earlier cultures.  Following is a basic description of the god Ehecatl as per Wikipedia:

“Ehecatl is a pre-Columbian deity associated with the wind, who features in Aztec mythology and the mythologies of other cultures from the central Mexico region of Mesoamerica. He is most usually interpreted as the aspect of the Feathered Serpent deity (Quetzalcoatl in Aztec and other Nahua cultures) as a god of wind, and is therefore also known as Ehecatl-Quetzalcoatl.  Ehecatl also figures prominently as one of the creator gods and culture heroes in the mythical creation accounts documented for pre-Columbian central Mexican cultures.  Since wind blows in all directions, Ehecatl was associated with all the cardinal directions. His temple was built as a cylinder in order to reduce the air resistance, and was sometimes portrayed with two protruding masks through which the wind blew.”

The main circular pyramid at Guachimontones has 4 staircases to its top, corresponding to the 4 cardinal directions.  The association with the Mesoamerican wind god is not irrefutable but it is strong here.  As there is no writing system at the site, or murals or public art illustrating a mythology, archaeologists can only make educated guesses as to the real ceremonial focus of this place.

Although mentioned briefly here and there, and largely unknown to even the most seasoned archaeologists specializing in ancient Mexico, it was only in the early 1970s that serious investigations began at Guachimontones.  At that time, the city was overgrown and in utter ruin, with many monuments either destroyed by time and the elements or by looters and those seeking building materials.  American archaeologist Phil Weigand and his Mexican wife, art historian Celia García, were the first to map and thoroughly study the site throughout the 1970s.  During one of their investigations García discovered a huge obsidian workshop which meant that Guachimontones was probably a commercial center and a trade hub in addition to being a place of ceremony.  The Weigand-García duo enlisted the support of archaeologists and archaeology students from the Colegio de Michoacán to begin the first formal excavations of the site.  Throughout the 1970s and 1980s Guachimontones had no formal protection from the state or national governments and as word spread of the finds at the site, looters descended on the ruins.  Intact sophisticated art objects made of clay and obsidian began making their ways into private collections in the US, Europe and Japan.  By the time that formal protection was given to the area in the late 1990s there was already great damage done to Guachimontones.  Here is an excerpt from the field diary of an American archaeologist named Chris Beekman who spent 10 months at the site in 4 different field sessions.  Part of his December, 1999 diary reads:

“The enormous looter’s trench into the central pyramid has been filled in, requiring 10 weeks of work, an average of 10 laborers working 6 days a week for 8 hours each day, to fill in a void in the pyramid’s center which had taken out 8-10,000 cubic meters of fill (approximately one fourth of the structure’s bulk).  We used wheel barrows and had all the fill at hand.”

Mexican archaeologist Efraín Cárdenas of the Colegio de Michoacán has been supervising most of the digs at Guachimontones since 1998.  Looting has decreased there, although the site was put on the United Nations’ World Monuments Watch List of the 100 Most Endangered Sites in 2008.  With more formal excavations and other research, the picture of what went on at Guachimontones in ancient times is becoming clearer and clearer.  Most of the site remains unexcavated and the ruins are still not very well-known to tourists.  There is a lot left to develop, discover and learn about this place.  What has been called the Teuchitlán Tradition may be reclassified by archaeologists sometime in the future as a distinct civilization with the gigantic circular pyramids at the center of Guachimontones as its focal point.
