Holtun, originally named La Máquina, is a Maya archaeological site located in the Petén Department of northern Guatemala on the road to Melchor de Mencos from Flores.Ponciano 1995, p.484. The city had a long period of occupation that lasted from the Middle Preclassic through to the Late Classic periods.IDAEH/AHT Engineering 1999, Anexo I-13. The site was officially recognized by the Guatemalan authorities in 1994 in response to reports from the local community of looting activity in the area. This looting had revealed large masks sculpted onto the side of one of the principal structures at the site. Holtun is the southernmost site in the Maya lowlands that is known to have such masks.Ponciano 1995, pp.488-489. The site is characterized by the presence of two particular architectural groups, consisting in a triadic acropolis and an E Group, which are markers of the sociocultural complexity of the Preclassic period in the Lowland Maya area. In addition, the nature of the karstic bedrock allowed for the creation of a great quantity of chultuns, which can be found in almost all of the architectural groups (Fialko, 2011: 479-483).

Location and etymology The site was originally named as La Maquina after the nearest village but was renamed as Holtun by Agustín Estrada Monroy, the then director general of the Patrimonio General Cultural y Natural (General Cultural and Natural Heritage). The new name is derived from the local Itza Maya language and means "stone head". The land surrounding the site has been completely deforested and is used for the cultivation of maize, beans and plantain, with ownership divided among the municipality and private landowners .Ponciano 1995, p.485.

The ruins of Holtun are located among a cluster of important Classic Period cities. Tikal is located to the northwest, Yaxha is to the north and Naranjo is in the same direction.

The site is located to the south of La Maquina village, in the municipality of Flores.Ponciano 1995, p.484. Ministerio de Cultura y Deportes #140. Holtun lies in a broken hilly region upon a karst ridge running from northeast to southwest. It is situated on a hilltop at an altitude of above mean sea level and is bordered on the south, east and west sides by three seasonal streams.Ponciano 1995, pp.484-485. There are no rivers passing very close to the site due to the local topography, with those watercourses to the south of the city draining toward lake Camalote some to the south. The Mopan and Salsipuedes rivers flow to the east of the lake, and the La Blanca lake is situated further south. The watercourses to the north of the ruins flow northward towards Laguna Yaxhá.

History The site was occupied from the Middle Preclassic period right through to the Late Classic period.

The archaeological evidence obtained from looters trenches and systematic excavations in the E-Group suggests that Holtun plateau was occupied during the Early Preclassic period. The ceramics obtained from the context include potsherds from Mamon horizon. The excavations at the Triadic Acropolis reveals an occupation around the Late Preclassicperiod, associated with the Chicanelhorizon. The Early Classic period occupation in Holtun was identified in the elite residential groups, particularly in the groups C, D, E and F. The Late Classic period was associated with architecture modifications for residential purposes. The ceramic evidence for the Terminal Classicperiod is minimum and comes from sectors associated with the main plaza near the Group C.Fialko, 2011: 478-481

Modern history Holtun was officially discovered in February 1994, when the Guatemalan Instituto de Antropología e Historia (IDAEH - "Institute of Anthropology and History") was notified of the looting of a previously unknown site between Flores and Melchor de Mencos. IDAEH investigators are estimated to have arrived at the site between six and eight months after looting had started, during which time the major architecture at the site had been damaged. The site was thoroughly surveyed by IDAEH's Department of Prehispanic and Colonial Monuments (Departamento de Monumentos Prehispánicos y Coloniales) in June and July 1994.Quintana Samayoa 1996, p.25. New archaeological investigations were initiated in 2010 by Brigitte Kovacevich and Michael Callaghan of Southern Methodist University.

Research Projects

The first official reconnaissance of the site was performed in 1994 by Erick Ponciano and the first map of the site was created.Ponciano 1995. In 1998 and 2001 respectively, two field seasons were performed looking for rescuing information from the previous looting practices. The result was a valuable documentation of the site and its archaeological traits, particularly the masks at the building facades and the Chultuns. The seasons were performed by personnel of Yaxhá project from the National Institute of Anthropology and History of Guatemala, and conducted by Vilma Fialko.Fialko, 2011: 478. In 2010 the first season of Holtun Archaeological Project, with the support of Southern Methodist University, perform the first field season. During this season, personnel of the project did an exhaustive reconnaissance and surveying, creating a new map of the site.Kovacevich et al. 2010. During the 2011 season, the project perform test pits in the plazas with the objective of collecting information to understand the ceramic sequence of the site. Also, the excavations pursued to understand the settlement pattern through the study of architectonic modifications in the plazas.Rivera Castillo, Ed. 2011. The season of 2012 consisted in the analysis of materials collected during the previous season, particularly ceramics, Obsidian and carbon samples for Radiocarbon dating.Kovacevich, Ed. 2012. During the next season in 2014, new test pits were done and the mapping project incorporates new land segments and archaeological traits. During this season, soil samples were taken to understand the chemical composition of the floors at the plazas through X-ray fluorescence analysis.Kovacevich and Cardona, Eds. 2015.

Mapping

Holtun has been mapped three times since the first reconnaissance in 1994. The first version of the map was created in 1994 as part of the first approaching to the site.Ponciano 1995: 491 The first survey reported 86 structures which were organized in four groups named with the literals A, B, C and D. The second map was created by the "Proyecto de Sitios Arqueológicos de Petén" (PROSIAPETEN).Fialko 2002 It was a revision of the original map which resulted in the identification of 115 structures organized in 14 major groups.Fialko 1999 The third map version was created by the Holtun Archaeological Project, which began the research in 2010. The project have been supported by the Department of Anthropology of Southern Methodist University . The map has been updated over three different mapping season, with the result of more than 200 structures identified and more than 27 chultuns.Rivera Castillo, Ed.: 264

Site description The sites consists of about 115 structures distributed largely along a north–south axis according to the local topography, with six architectural groups. The four principal groups are located upon hilltops, with two other groups in dry lower areas not subject to seasonal flooding. The four main groups have been labelled A–D by archaeologists.

Group A This group is the largest group at the site, located at the extreme northern end.

Structure A-1 is a massive basal platform that measures and stands high. Standing upon this platform is another, smaller platform (A-2) and two structures (A-3 and A-7). These two structures flank a patio with a surface area of approximately . The smaller upper platform supports three further structures laid out around a patio with an area of . The whole complex faced southwards and has been identified as a Late Preclassic triadic pyramid structure.Ponciano 1995, pp.485-486, 489, 491.

Structure A-2 is smaller platform standing upon Structure A-1. It measures by high and is decorated with two large masks on its south face, fashioned from stone and stucco.Ponciano 1995, pp.484-485, 491. Quintana Samayoa 1996, p.25. IDAEH/AHT Engineering 1999, Anexo I-13. These masks were revealed by an enormous looters' trench and gave rise to the name of the site. One of the masks is anthropomorphic and the other zoomorphic, although both have jaguar features.

Structure A-2 supports 3 additional structures (A-4, A-5 and A-6).Ponciano 1995, pp.485, 491.

Structure A-3 is a mound on the south side of the main platform, it is flanked by structure A-7 and the two together limit access to the platform.

Structure A-4 stands upon the upper platform and measures approximately high.

Structure A-5 is another structure standing upon the upper platform. It measures approximately high.

Structure A-6 also stands upon the upper platform and measures approximately high.

Structure A-7 is another mound on the south side of the main platform, it is flanked by structure A-3 and the two together limit access to the platform.

Structure A-8 is a large pyramid south of Structure A-1. It measures and supports a number of smaller structures (A-9 through to A-20) enclosing a courtyard with an area of . The structures have an average base width of and an average height of high.Ponciano 1995, pp.486, 491.

Structure A-9 is the largest building standing on Structure A-8.

Structures A-21 to A-24 are four low mounds with an average height of . They are located to the east of Structure A-8.

Group B

Group B is situated south of Group A. The group consists of two small clusters of buildings grouped around their respective plazas and contains a number of chultunob (subterranean storage chambers).

Structures B-1, B-2 and B-3 enclose an interior patio on the north, west and south sides respectively. These structures measure .

Structure B-4 is a small basal platform situated to the east of structures B-1 to B-3.

The south plaza of Group B has an area of and is enclosed by a number of structures.

Structure B-5 is on the north side of the southern plaza in Group B. It measures and stands high.

Structures B-6 and B-7 are on the east side of the south plaza.

Structure B-8 is a range structure enclosing the south side of the plaza.

Structures B-9 and B-10 are on the west side of the south plaza.

Group C This group lies southeast of Group B and includes 29 structures, most of which are clustered on an artificially levelled hilltop.

Structure C-1 is a small mound on the north side of the group, it is associated with a nearby chultun.Ponciano 1995, p.486.

Structures C-2 through to C-5 are part of a compact and formally arranged complex measuring and form a T-shape as seen from above. The complex measures high.

Structure C-6 is on the east side of the complex and measures .

Structure C-7 is the largest structure in the group and measures square with a height of . It is on the south side of the complex.

Structure C-8 is on the east side of the complex and measures . It stands high.

Structures C-15 to C-21 are long structures measuring up to lying to the south of the group. The appear to be parapets enclosing an avenue running south to another cluster of buildings.

Structures C-22 to C-29 form a well-defined cluster arranged around a central courtyard lying to one side of a possible causeway running southwards from Group C to Group D. Most of these mounds are quite small, with only Structures C-22 and C-25 being of a larger size, measuring in diameter and high. The whole complex is located upon an artificially levelled platform; the central courtyard has an area of .

Group D Group D is located to the south of Group C and is linked to it by a wide causeway that runs for .Ponciano 1995, pp.486-487, 491.
