Chunchucmil was once a large, sprawling pre-Columbian Maya city located in the western part of what is now the state of Yucatán, Mexico.

Although the famous explorer and author John Lloyd Stephens traveled within a few kilometers of Chunchucmil during his historic journey across the Yucatán Peninsula (he even met with the owner of the nearby haciendas),Stephens 1962 (1842). the archaeological site went relatively unnoticed by Maya scholars for more than a century because virtually no monuments (stelae) or other grand sculptures have been found there. The lack of royal monuments, combined with other archaeological data, may indicate that Chunchucmil was not a city ruled by a single divine king, as most other Maya polities. Instead, it may have been a commercial center, organized by various lineages and focused upon funneling goods between regions—such as the trade between the Gulf of Mexico and the interior of the Yucatán Peninsula.

Chunchucmil was most populous in the Middle Classical Period (400–650 AD), with an estimated 31,000–43,000 (within the central 25 km2 area) people.

Site characteristics

Location The site center is located ca. 27 km (16.8 mi) inland from the Gulf of Mexico and approximately halfway between the coast and the next largest archaeological site of Oxkintok. It was named in the late 1970s after the nearest modern settlement (the Hacienda and village of Chunchucmil), however the archaeological site is so large that it extends onto the ejido lands of at least five modern communities: Chunchucmil, Kochol, San Mateo, Coahuila and Halachó. The majority of the ancient Maya site is located within the municipality of Maxcanú, however a portion of it is situated on land pertaining to the municipality of Halachó.

Environment and ecology The site of Chunchucmil is located on a narrow band of semi-arid terrain that parallels portions of the western and northern coastlines in Yucatán and Campeche. This particular environmental zone is considered the driest in all of the Maya area,Luzzadder-Beach 2000.Dahlin et al. 1996. with less than 800 mm (31.5 in) of annual rainfall.Beach 1998. Compounding these harsh conditions, nearly fifty percent of the surface around Chunchucmil is exposed limestone bedrock. Even when soils are encountered, they are rarely more than a few centimeters in depth. Vegetation in this region is generally considered scrub forest dominated by acacia and other drought-resistant species (similar to the European heathland). One of the mysteries surrounding Chunchucmil is how such a large city could have sustained itself in one of the poorest regions for agriculture.Vlcek et al. 1978.Farrell et al. 1996.

However, the ancient city was situated at the edge of this semi-arid ecological zone, exactly where the dry Yucatecan plains dip and fracture into vast wetlands (see map). Immediately to the west of Chunchucmil are found the seasonally inundated savannas, fresh water petenes (or ojos de agua), and eventually the brackish mangrove estuary where the Yucatán aquifer empties into the Gulf of Mexico near the ancient Maya coastal site of Canbalam. It is likely that ancient Chunchucmil was purposefully situated to take advantage of multiple ecological zones, including coastal resources such as the salt-beds of the Celestún peninsula, and to increase accessibility to the vigorous circum-peninsular canoe trade route of Pre-Columbian times, using Canbalam as its port of entry.Dahlin et al. 1998.

Etymology The term "Chunchucmil" was originally used to name a freshwater well (Ch'en Chun Chukum), the central water source for the cattle ranch that eventually grew to become the historic henequen hacienda of Chunchucmil. Most wells in this region are named after animals or plants. In this case, the words Ch'en Chun Chukum literally mean "the well at the base of the Chukum tree" (Havardia albicans). Local Maya speakers still refer to the modern village of Chunchucmil as Chun Chukum when speaking in their native tongue. The ancient Maya archaeological site was given the name Chunchucmil by archaeologists in the 1970s because that was the closest modern community to the site center.Garza & Kurjack 1980. Local Maya villagers today do not have a single term to refer to the ruins, since the ancient city is so large that it encompasses most of their lands.

Site size The exact size of Chunchucmil is currently being studied using aerial photography, satellite imagery, and survey transects by the Pakbeh Regional Economy Project (who have been working at Chunchucmil since the mid-1990s, under the direction of Dr. Bruce H. Dahlin). Estimates range from 25 km2 for the more compact urban settlement to around 64 km2 for the city and its adjoining suburbs and farmsteads.Hixson 2005. In either case, this places the site of Chunchucmil among some of the largest and most densely settled ancient Maya polities.

Chronology Ceramic data indicate that the Chunchucmil region was occupied from the Middle Preclassic (Middle Formative) through the Postclassic periods of Maya prehistory. However, widespread test excavations within the architectural groups of ancient Chunchucmil indicate that the city reached its apogee during the latter part of the Early Classic and the early part of the Late Classic, attaining its maximum spatial extent, population, and structural density. This period is defined in some areas as the "Middle Classic."Varela 1990; see also Ardren 2000; Stanton 2000; Dahlin & Mazeau 2002, 2004, and Hutson et al. 2005, 2006. Chunchucmil appears to have gone into decline during the latter part of the Late Classic. The Terminal Classic (or Puuc) occupation at Chunchucmil is ephemeral at best, and the Postclassic occupation at the site consisted of squatter-like settlement. A few early colonial homesteads have been found, but the region was largely abandoned between the Maya Postclassic period and the beginnings of the cattle ranches and henequen haciendas of historic and modern times.

Built environment

Monumental architecture The Classic Period site center of Chunchucmil is dominated by over a dozen pyramids ranging in height from 8 to 18 m (26 to 60 ft) tall. Each pyramid is part of a structural arrangement referred to as a "quadrangle group" by members of the Pakbeh Regional Economy Project. Quadrangle groups consist of an enclosed courtyard flanked by a pyramid on one side (which faces inward towards the courtyard) and a number of ranged and compact structures along the remaining three sides. Within each quadrangle group's courtyard is a small central platform that is interpreted as a focal point of ritualized activities (such as an altar). Other ceremonies would have taken place within the temples atop each pyramid. With the temple pyramids and central platforms acting as loci of lineage-based ritual, quadrangle groups likely housed the upper-echelon elites of ancient Chunchucmil that may have been active in the socio-political, ideological and economic administration of the city.Dahlin & Ardren 2002. Of particular importance is the fact that each major quadrangle group is connected to the others through a network of sacbeob (stone causeways), suggesting an unknown degree of connectedness between the residing lineages and (potentially) cooperation or competition in ruling Chunchucmil. If this was indeed the case, Chunchucmil's political structure may have been roughly analogous to that suggested for the later Maya capital of Chichen Itza, referred to as a "multepal" system and characterized as rulership through council.Sharer & Traxler 2006:581.

Residential architecture Residential architecture at Chunchucmil often follows the same pattern as the large quadrangle groups, with structures arranged on four sides of a small plaza. This arrangement conforms to the "patio cluster" or "patio group" model for Maya residential organization, where two or more structures, potentially housing multiple family units, face a shared patio or courtyard.Ashmore 1981Wilk 1988:143

At Chunchucmil, these clusters of associated structures are encircled by low-lying stone walls (called albarradas), that demarcate domestic space by bounding the group's residential lot or yard (called a solar). The entire unit, consisting of the architecture and the associated solar, is today referred to as an "albarrada group". Unlike at the vast majority of Maya sites, Chunchucmil's albarrada groups contain clear boundaries between residential house lotsVlcek 1978. and, as of result of this, researchers are better able to study such issues as settlement patterns, occupational density, population estimates, lineage structure, and social organization.Hutson et al. 2004.Hutson et al. 2006.

Many residential groups had a small temple or shrine (similar to the placement of the temple pyramids of their larger counterparts). These buildings served as loci for the performance of household rituals or other types of ideological practices.Magnoni et al. 2004. One such residential shrine that has been excavated and consolidated at the Lool Group revealed its form to be talud-tablero. This style of architecture is most famous at sites in Central Mexico, such as at the contemporaneous city of Teotihuacan. Beneath the stair of this shrine was a vessel that also replicated the pottery of that Central Mexican city. While this should not be used as evidence of direct Teotihuacan influence, it does suggest Chunchucmil's participation in the greater Mesoamerican communication sphere at the time of Teotihuacan's dominance. All other structures excavated at Chunchucmil thus far lack demonstrable Teotihuacan influence.

Transportation arteries One of the distinguishing characteristics of Chunchucmil is its network of stone-lined paths. As mentioned above, the majority of residential lots are surrounded by albarradas (stone walls) that, when viewed on a map, give the site a honeycomb appearance. The space between adjacent albarradas form avenues or paths for foot traffic (called callejuelas, see photo) that radiate outward from the site center and into Chunchucmil's dense residential zone. By mapping these formations, researchers have been able to better understand the flow of traffic in and out of the site center as well as the relationship between Chunchucmil's central core, its residential urban sprawl, and its outlying peripheral settlement.

Beyond Chunchucmil, in the seasonally inundated western wetlands, researchers have found a network of rock alignments that connect Chunchucmil's periphery to other outlying settlements. Such rock alignments, called andadores by Maya archaeologists, would have provided sure footing through the wetlands, like stepping stones, leading travelers to various towns and resources in Chunchucmil's hinterland. While not all of these andadores have been followed to their final destinations, the general orientation of the longest alignments suggest that they may have functioned to connect Chunchucmil with the coast near Canbalam.see report chapters by Hixson in Ardren 2000; Stanton 2000; Dahlin & Mazeau 2002, 2004; and Hutson et al. 2005, 2006.
