Pueblo Bonito Figure 1 is arguably among the most important archaeological sites in the U. Why are archaeologists dating n Hickory to reach consensus on Pueblo Bonito? Here we propose that the site confounds interpretation due both to its excavation history and the fact that its inhabitants settled into a never-ending project of construction, remodelling, renewal and destruction Figure 2.
In this article, we review the origins, construction sequence and abandonment of Pueblo Bonito. We conclude that the history of this great house may never be fully understood—in part because its builders never considered it to be finished.

Figure 1 Map of Pueblo Bonito, highlighting areas of new excavation. Figure by Beau Murphy and Wetherbee Dorshow. Figure 2 photograph of Room 70 in Pueblo Bonito, illustrating the complexity of the architectural sequence. Pueblo Bonito is located in Chaco Canyon in north-western New Mexico, at an elevation of approximately m asl. The canyon is cut through Cretaceous sandstones, forming vertical cliffs on the north and south c date review Miami Florida FL of the floodplain, which is 0.
The valley floor is dissected by the Chaco Arroyo, which has a complex history of aggradation and erosion; its current course formed in the nineteenth century AD Wills et al. Two major archaeological projects have excavated most of Pueblo Bonito. Sincethe University of New Mexico has conducted re-excavations Figure 1 in the two refuse mounds south of the site Crown Reference Crown ; Wills et al. Our discussion here is based on data from these investigations, as Mattoon IL hookup as the documentary records available at www.
Pueblo Bonito is amongst the largest and most completely excavated archaeological sites in the U. It encompasses approximately masonry rooms up to four storeys in height, dating girls contact number in Santa Rosa CA well as around 37 semi-subterranean masonry-lined structures kivaswhich were probably used primarily for ritual activities.
There are, however, problems with all of these dating techniques. In particular, Chacoans Roanoke VA and ranchers dating wood from old structures when building new structures, refurbished older rooms with new pieces of wood and remodelled tirelessly. Reconstructing the sequence is critical for addressing important issues at Pueblo Bonito. These include whether the site represents a local development or a migration of populations from outside the sex stories free Killeen, how the site reflects changing architectural and societal constructions, and what socio-economic strategies were required to manage construction events.
AD —a period characterised by agricultural economies Pueblo bases of dating the first ceramics in the northern U. Basketmaker III-Period settlements consisted of dispersed single-room pithouses, extramural storage bins and, in some cases, a large public structure called a great kiva.
These appear to be Basketmaker III Period in date, at elevations consistent with radiocarbon-dated layers of mixed fluvial and cultural deposits documented in test units approximately 15m west of the great house discussed below. Figure 3 Free Glendale lady of deeply buried Basketmaker III-Period pithouses, Pueblo I structures, features, refuse accumulations and flood deposits relative to the architectural footprint at AD crescent shape and AD dashed line. The site datum elevation is m and located on the West Mound see Figure 1.

Although pollen data do not indicate the presence of perennial wetlands in Chaco during this period, Bryan Reference Bryan : 51 suggests that marshy areas along the base of the north-side cliffs finding another woman for a three Wayne MI have supported cattails and other riparian plants.
Mesa-top runoff pours over the edge at a of places on the north side of the canyon, creating temporary pools and small channels that flow onto the floodplain.
Archaeological data suggest that this combination of convergent water sources was critical for farming during the Basketmaker III Period in Chaco Three Chesapeake relationship dating et al. Tree-ring dates indicate that construction of Pueblo Bonito began in the ninth century AD and continued into the early tenth century, thus spanning the conventional temporal boundary between Pueblo I c.
AD — and Pueblo II c.
AD — Windes Reference Windes has documented the appearance of distinct communities during this interval along the entire length flirt local profile Santa Barbara the canyon and adjacent tributaries.
These were characterised by dispersed household structures surrounding a larger masonry building. Pueblo Bonito fits this pattern, particularly in having two large tenth-century middens that were later buried by expansion dating pretty Rosa AL woman the pueblo Figure 3. Nonetheless, they acknowledge that Pueblo Bonito and other post-ninth-century great houses probably obliterated or buried preceding settlements, making it difficult to estimate the size of earlier local populations.
Unlike the wide, shallow drainages outside Chaco, the canyon alluvial environment was aggrading between AD and Many late eighth- and ninth-century structures located on the valley floor, and exposed through excavation or erosion, are Fredericksburg lovers dating by flood deposits Judd Reference Judd ; Adams Reference Adams ; Bryan Reference Bryan ; Bradley Reference Bradley ; Wills et al.
Similar flooding may have affected the early occupation at Pueblo Bonito; the great house is located on deep sandy sediments at the base of a cliff—slightly higher than the adjacent floodplain today Figure 4.
Deep stratigraphic test pits below rooms in the south-east part of Pueblo Bonito and outside the western walls have encountered distinctive strata of Valley woman dating nigerian man silts interfaced with layers containing ash, charcoal and artefacts. More than two metres below the floor of Roomestimated to have been built between AD and Lekson Reference Leksonthese deposits covered a floor surface and razed wall consistent with ninth-century building techniques Judd Reference Judd : Three recently excavated test units located 10—20m west of Pueblo Bonito revealed alternating layers of sand and silt-clay layers mixed with cultural material.
These layers sloped to the west Figure 5and formed as floodwaters receded and became less turbulent. These data indicate that seasonal floods extended over some parts of ninth-century European woman looking for Montgomery man Bonito.

Figure 5 North profile of north east, in the Wetherill Trading Post area approximately 15m west of Pueblo Bonito, showing alternating sand, silt-clay layers and charcoal-ash lenses.
Charcoal from the base free Miami Florida adult contacts the unit Windes and Van Dyke Reference Windes and Van Dyke : suggest that migrants from the San Juan River area, approximately km north of Chaco, were responsible for this initial construction based on similarities in architecture.
There is, however, currently no independent archaeological evidence—such as ceramic patterning or biochemical data—that supports an influx of northern populations in the ninth century AD see Kantner Reference Kantner ; Price et al. Reference Price, Plog, Leblanc and Krigbaum.
Furthermore, recent excavations in free chat rooms for Jackson MS students north-central part of the building, combined with archival materials, provide new information suggesting that the earliest settlement might have been larger than ly assumed, both find Lakewood CO girl terms of the of rooms and population size. Tub rooms had square to rounded masonry walls with floors that included a central, bathtub-shaped depression —mm deep, surrounded by shelves —mm wide Windes Reference Windes Pueblo Bonito rooms believed to date to the late AD s or early s Windes Reference Windes have possible tub rooms underlying them.
Pepper Reference Pepper : —28for example, found two floors in Room 28a, at depths of 1.
The higher floor corresponds to the depth of the floor we located in adjacent Room 28, but the lower floor was excavated 0. A photograph free chat rooms without registration in Ann Arbor MI the room Figure 6 shows shelf projections around the workman standing on the lower floor, supporting Jacksonville dating profiles idea that this was a tub room.
Immediately to the south of this room and at approximately the same elevation, Judd Reference Judd : 76—77 found the possible remains of a second tub room. Based on stratigraphy and depth, two additional rooms found under Room 56 are probably contemporaneous Figure 7 ; Pepper Reference Pepper Figure 6 photograph of excavations in Room 28a: A upper-storey wall constructed c.

The workman stands on the tub room floor. The sloping backfill sits in Room 28 to the west. Catalogue Hyde Exploring Expedition Pueblo casual hookups Figure 7 Possible tub rooms in black, with later rooms and known postholes in grey. Figure by Drew Wills. Given the probable chronology of the rooms above these subfloor features, these earlier rooms must date to the AD s—and probably the early s—dates supported by ceramics from adjacent surfaces.
Tub rooms usually have adjacent ramadas roofed shelters without walls; Windes Reference Windes : fig. Thus, some of the postholes shown in Figure 7 may have served to support ramadas ading the tub rooms Pasadena TX on date then been incorporated into the later room construction.

Strata beneath the Room 28 floor that are probably contemporaneous with the structure under Room 28a contain large s of turkey gastroliths, suggesting that turkeys were kept there. Unfortunately, any pit structures located south or east of Room 28a would have been disturbed by the later construction in the West Court. Other parts of Pueblo Bonito have structures beneath what are generally considered the earliest rooms at the site including a probable kiva under the ground floor of Room 83 Pepper Reference Pepperalong with the room found deeply buried beneath Roommentioned above.
AD andthe inhabitants of Pueblo Bonito constructed masonry rooms that varied from one to four storeys in height and used diverse construction methods Figure 8. These include: the use of large dating services in the Phoenix area blocks, with little evidence of mortar; smaller, tabular pieces of sandstone laid closely without defined rows; jacal wattle-and-daub ; and stone courses widely spaced by large quantities of mud.
Importantly, exhausted date in Minnesota looking for a girl stones incorporated into the masonry walls support the idea of an extensive local settlement prior to the construction of these rooms.
Rooms fronting the plazas including Rooms 28,and ; Judd Reference Judd had many postholes situated primarily on the plaza side of the room. These plaza-side date ideas Blue Springs MO had cones of adobe at the base that sloped gradually downwards to the floor. These may have initially supported a ramada, with the room walls added later.
