Other Anasazi Timelines


1700

Christian coverts were massacred at Polacca Wash on Hopi lands in AD 1700. "There's no doubt they were cannibalized." From In Search of the Old Ones, by David Roberts.

[Remains of] some thirty murdered Puebloans [were unearthed] at Polacca Wash, below First Mesa. To [Turner’s] surprise, the criteria for cannibalism fit. A radiocarbon date placed the remains within a range close to A.D. 1700. “I’m ninety-five percent sure that the massacre at Polacca Wash represents the captives from Awatovi,” Turner told me. “And there’s no doubt they were cannibalized.” Roberts/Old Ones, p. 162

Hopi oral tradition says the chief of Awatovi was so upset with the tide of conversions to Catholicism that he ordered his own village massacred. From In Search of the Old Ones, by David Roberts.

In the year 1700 [the Hopi village of] Awatovi saw a tide of conversions to Catholicism… The Hopis’ own oral tradition tells that Ta’polo, the chief of Awatovi, grew so upset with the transformation of his village that he plotted in secret with the men of [the neighboring villages of] Walpi and Oraibi to wipe out his own town. One morning in late autumn 1700, the warriors attached when all the Awatovi men were inside their kivas; the attackers pulled up the ladders, set fire to the kivas, and burned the men alive. The whole village was razed….The tradition says further that a band of surviving men, women, and children was marched toward First Mesa, when a dispute broke out between Walpi and Oraibi men over the disposition of the captives. Out of spite, the victors killed many of the prisoners and left their carcasses on the ground. Roberts/Old Ones, p. 161

1500

By this time, Southwest populations had declined to levels of the eighth and ninth centuries (Lekson, p. 189)

By this time, no vestige remained of that earlier Anasazi political world: there was no longer any central government (Lekson p. 197)

1450

Paquimé’s fall, though it could be as late as 1500 (Lekson, p. 26)

Just about everyone (in former Anasaziland) was gathered into about a hundred large towns, clustered at Hopi, Zuni, Acoma, and Laguna in the Rio Grande Valley from Socorro in the south to Taos in the north — a very big change (Lekson p. 194)

After this date, dramatic decline in Pueblo towns; things grew much worse after European intrusion; more than fifty large Rio Grande pueblos were abandoned in historic times, leaving only twenty today (Lekson p. 197)

Little left of Hohokam’s earlier glories (Lekson p. 246)

Before this date in the south, ethnography has little useful to say (meaning oral stories of descendant puebloans has little value) (Lekson p. 249)

1345

Arroyo Hondo abandoned (Stuart)

1340

“The tree-ring reconstructions show that at 1300 to 1340 it was exceedingly wet,” said Larry Benson, a paleoclimatologist with the Arid Regions Climate Project of the United States Geological Survey. “If they’d just hung in there…” Though the rains returned, the people never did. —“Vanished: A Pueblo Mystery,” by George Johnson, April 8, 2008, The New York Times

1335

Precipitation declined around Arroyo Hondo (Stuart)

Arroyo Hondo Pueblo, five miles south of Santa Fe at 7,100 feet, was founded; by 1330 the site was immense with more than 1,000 rooms (Stuart)

1300

Who Were the Anasazi on BLM.gov

There never was an “Anasazi tribe”, nor did anyone ever call themselves by that name. Anasazi is originally a Navajo word that archaeologists applied to people who farmed the Four Corners before 1300 AD. (BLM)

By this date, natural conditions (precipitation — the lack of) had forced Chacoan survivors to a few sites along rivers (Stuart)

By this date, only the best-watered east-facing canyons and slopes were still inhabited (Stuart)

Early this century, masked rain gods and the kachina cult, thought to have originated west of the Zuni area, began to penetrate the eastern pueblos and displace many older religious customs (Stuart)

Mid-century: Violence on the southern frontiers seems to have been largely sorted out, and settlements shifted downhill to the rivers’ open floodplains (Stuart)

By this time the Anasazi heartland (around modern Four Corners) was empty (Lekson, p. 23)

Cahokia was empty and derelict (Lekson, p. 152)

By this year, northern Chihuahua was one of the most densely settled areas in the southeast (compared to essentially empty at 1200) (Lekson, p. 176)

A watershed year, a demographic zenith for the Southwest, followed by catastrophic population decline, nearly complete reorganization of peoples and polities, and then centuries of colonization (by the Spanish) (Lekson, p. 189)

The Mexica, who would become the Aztecs, arrived in the Valley of Mexico from the north (Lekson, p. 191)

After this time, most Pueblo IV towns had only two or three large kivas — something happened around this time to radically change basic Anasazi house/village form (Lekson p.195)

End of migrations out of the Four Corners (Lekson p.195)

After this date until 1450, dramatic growth for Pueblo towns (Lekson p. 197)

T-shaped doors all but gone from the Plateau and Pueblo region, only to reappear throughout Paquime (Lekson p. 211)

Before this date in the north, ethnography has little useful to say (meaning oral stories of descendant puebloans has little value) (Lekson p. 249

Pueblos developed after this time as a reaction to state-level governments, conscious rejections of earlier hierarchies. They deliberately replaced the kings of Chaco with the priests of Zuni. (Lekson p. 251)

to 1500s

Galisteo basin pueblos controlled most of the turquoise trade by controlling Mount Chalchihuitl (“turquoise mountain”) in the Cerillos Hills — the Aztecs of Mexico actually had a place glyph for this mountain (Stuart)

to 1350

Population peaked across the whole Southwest, then plummeted sharply (Lekson, p. 189)

to 1340

“The tree-ring reconstructions show that at 1300 to 1340 it was exceedingly wet,” said Larry Benson, a paleoclimatologist with the Arid Regions Climate Project of the United States Geological Survey. “If they’d just hung in there…” Though the rains returned, the people never did. —“Vanished: A Pueblo Mystery,” by George Johnson, April 8, 2008, The New York Times

1295

“Fully half the Anasazi domain had been abandoned around 1295 and never reoccupied.” (Roberts p. 213)

1286

Last construction date for Keet Seel (Roberts p. 105)

1285

Salmon abandoned by Mesa Verdeans (Frazier p. 135)

1280

The Anasazi occupation of the Four Corners lasted until 1280. The Nazi occupation of France lasted until 1944. From Who Were the Anasazi on BLM.gov.

It’s interesting that the BLM uses the word occupation. The Anasazi occupation of the Four Corners lasted until 1280. The Nazi occupation of France lasted until 1944.

The last villagers left Mesa Verde (Lekson, p. 163)

1276

to 1299

The great Chaco Canyon drought (Roberts p. 151)

The Great Drought (Lekson, p. 143)

1275

After this date, the erratic and declining rainfall turned into a series of deep, localized droughts (Stuart)

Even worse drought hit Anasazi region and violence spun out of control (Lekson p. 239)

1275

To enforce its failing rule [after yet another drought began in 1275], Aztec unleashed lethal force. At farmsteads, squads of warriors fell upon families failing in their duties, old and young. They were executed to intimidate other villages that might be thinking of slipping Aztec’s yoke. Men, women, and children were brutally and publicly killed and left to rot, unburied, in the ruins of their homes. These horrible scenes replayed a score or more times, but even terror could not hold Aztec’s failing polity together. —A History of the Ancient Southwest, by Stephen H. Lekson, p. 239. Image of Anasazi warriors from a website with no clear name displaying a Reproduction by Thomas Baker of an Anasazi Indian kiva mural unearthed at Pottery Mound, New Mexico.

1275 to 1300

The Great Drought brought Sinagua to collapse (source?)

1250

After this time, precipitation became more erratic (Stuart)

By this decade, trade across the region increased (Stuart)

Defenses against Anasazi Nazi-like warriors, from In Search of the Old Ones, by David Roberts.

“Around 1250, you see an incredible change. Everybody’s moving into the canyons, building cliff dwellings. At Sand Canyon, 75% of the community lived within a defensive wall that surrounded the pueblo. All through southeastern Utah, northeastern Arizona, southwestern Colorado, the same thing’s happening. Suddenly, at 1250, the trade ware goes to zero. Before that, you had plenty of far-traded pottery, turquoise, shells, jewelry. Suddenly, nothing. And right at 1250, the ceramics revert from Mesa Verde-style pitches–tall, conical vessels with rounded bulblike bases–to the kinds of mugs made at Chaco 200 years earlier.” (Roberts from Bruce Bradley of Crow Canyon Archaeological Center, p. 150-151)

Construction start date for Keet Seel (Roberts p. 105)

A general breakdown in annual predictability of precipitation made farming increasingly chancy (Lekson, p. 162)

Paquimé rose to prominence (Lekson, p. 172)

After this year, platforms became elite residences (Lekson p. 202)

In the decades after this time, Chacoan ruling families were looking for someone to rule. Hohokam needed leaders and the Platueau had a surplus (Lekson p.203)

1250 to 1500

Casas Grandes in northern Mexico as center of Chacoan culture (Frazier p. 234, from Lekson)

1250 to 1450

Great migrations shifted tens of thousands of people acros the region, shaping a new Southwest (Lekson, p. 190)

All across the Pueblo world, from Hopi to the Rio Grande, population increased, doubtless from relocations from the Four Corners (Lekson p. 197)

1250 to 1450

Hohokam towns spread over large areas, prefiguring the urban sprawl of modern Phoenix (Lekson p. 210)

1230

1230 to 1240

This decade, Anasazi society regrouped and aggregated into sites in the northern Rio Grande, typically at 6,600 to 7,300 feet in elevation; all were built to withstand attack; some were attacked, leaving much evidence of violence such as skulls caved in my hard blows and burning, but no looting of valuables, suggesting an attempt to drive them away or rid the country of the people (Stuart)

1230 to 1260

Large new pueblos such as Bayo Canyon Ruin near Los Alamos were constructed on hundreds of mesa tops through the Southwest (Stuart)

1223

Mean date of pit house communities (average six pit houses) in eastern Arizona, Taos, Santa Fe district, Apache Creek [?], Cebolleta Mesa [?], and in the Sierra Blanca near Ruidoso, NM; evidence of pottery trade is substantial, with more than a dozen types at many locations (Stuart)

1200

Early this century, trade was reestablished across the four-corners region (Stuart)

Mesa Verdeans cliff houses flourished this century (Stuart)

Most skeletons from this century are marked by evidence of overwork and an inconsistent food supply (Stuart)

Or perhaps as early as 1125, Chaco Canyon culture had collapsed (Roberts p. 161)

Rock art depictions in Four Corners region of the feathered serpent, or Quetzalcoatl (aka Xipe Totec to Toltecs; aka Maasaw to modern Hopi)

Before this time, Anasazi villages were almost always small and short-lived, with the important exception of Chaco Canyon (Lekson, p. 137)

By this year, the arc of Pueblos — Hope in the west through Zuni and Acoma to the norther Rio Grande on the east, was well settled (Lekson, p. 163)

1200 to 1230

Known as the Little Ice Age in Europe; it probably got colder and wetter in the American Southwest as well (Stuart)

1200 to 1250

Precipitation increased in quantity and reliability enough to provide some surpluses of food supply (Stuart)

1200 to 1300

Late Pueblo III; Mesa Verde Phase; Pots: Mesa Verde black-on-white, indented corrugated (rock & sherd); major re-population (Tom Windes)

Mogollon culture begins moving into the Hopi-Zuni region (Martin, p 21)

1190

1190 to 1206

Balcony House at Mesa Verde constructed (Frazier p. 77)

1190 to 1260

Construction of all of the cliff dwellings including Mesa Verde, Bandelier National Monument, Gallina highlands, Chuska Mountains, Montezuma Castle, Mavajo National Monument in Arizona, and Gila Cliff Dwellings in Mogollon country; most were inhabited less than 100 years (Stuart)

1185

Salmon reoccupied by Mesa Verde people (Frazier p. 135)

1170

By this decade, the Chaco culture was but a memory (Stuart)

Civil war resulted in fall of Tula, capital of the Toltecs, followed by anarchy

Fighting abated in the highland regions around Chaco Canyon this decade (Stuart)

This decade, small pueblos founded at higher elevations with no sign of palisades or defensive measures, none built on cliffs; fewer had kivas; mineral-based paint on pottery replaced by organic paint from burnt plant material  (Stuart)

1168

The Toltec capital Tula was destroyed by successive new tribes of barbarians coming from the north, among them the Aztecs (Waters p. 117)

1150

Aztec abandoned (Frazier p. 131)

Many Hohokam sites abandoned and relocated, about the time platform mounds replaced ball courts (Lekson, p. 23)

Many Mogollon districts abandoned (Lekson, p. 24)

Hohokam crashed (Lekson, p. 80)

No ball courts (Hohokam) were built after this time

T-shaped doors first appeared at Chaco Great Houses, but not commoner dwellings) (Lekson p. 211)

After this date, T-shaped doors showed up at Aztec Ruins (Lekson p. 211)

Hohokam ball courts replaces by platform mounds (Lekson p. 240)

After this time, everything sagged south, with migrations out of the northern Plateau bumping people of the southern Plateau farther south into the Mogollon uplands (Lekson p. 241)

This year, give or take a decade, was a rough one for North America — Tula fell, Cahokia and Chaco crashed, and Hohokam fell apart (Lekson, p. 150)

Fall of Toltecs in 1150 kicked off Anasazi Nazi-like culture, from A History of the Ancient Southwest, by Stephen H. Lekson

Tula [Toltecs] fell about 1150. [W]ith Tula’s end, the Post-Classic pattern came into focus in vibrant clarity: expansive politics, long-distance dynamics, power plays and upheavals, and a swirling world of migrations, invasions, expulsions, and fragmentation. —Lekson p. 242

Anasazi Nazi-like culture, from A History of the Ancient Southwest, by Stephen H. Lekson

1150 to 1300

The events of 1150 to 1300 [spelled] the end of Tula [Toltecs] and consequent regional reorganization marked by audacious long-distance trade and flamboyant political adventures. —Lekson p. 144

1150 to 1200

Wars of attrition and atrocities spread across the Chacoan world (Stuart)

1150 to 1300

Cahokia fell gradually (Lekson, p. 115)

Cahokia rose and began a precipitous decline (Lekson, p. 152)

1145

Construction began at the Wupatki Great House, perhaps as a rival to the northern San Juan, especially Aztec Ruins (Lekson, p. 157)

1140

“The Great North Road: a Cosmographic Expression of the Chaco Culture of New Mexico,” by Anna Sofaer, Solstice Project; Michael P. Marshall, Cibola Research Consultants, Corrales, New Mexico; and Rolf M. Sinclair, National Science Foundation, Washington, DC.

1139

Last known construction at Salmon (Frazier p. 205, although it’s written as “1239,” which I believe is a typo)

Founded just before 1100, Salmon was a Chacoan refuge until a number of its women and children were burned in the tower kiva that once arose from the main block. —Anasazi America, by David E. Stuart, p. 105. It was apparently attacked and more than 30 women and children who had sought refuge in its impressive tower kiva died horribly in a fire set to destroy the town [in about 1130]. —Anasazi America, by David E. Stuart, p. 136. Aerial view of Salmon Ruins from The Foxworthy Traveling Show.

After the drought of this year, tens of thousands of farmers and others displaced from shrinking great houses and fled to the uplands, including Chuska and Lukachukai mountains to the west, Mesa Verde and San Juan ranges on the north, Gallina highlands on the east, the foothills of Albuquerque’s Sandia and Manzano mountains on the southeast, and Cebolleta Mesa, the El Morro district, and the Zuni Mountains to the south [odd, then, that CR was abandoned this same year] (Stuart)

Beginning of severe drought that lasted 50 years (Frazier p. 205)

Doyel proposes that a prolonged and severe drought brought more than 250 years of Chacoesque development to an end

Fifth and last major construction period for Pueblo Bonito (Frazier p. 77)

Salmon abandoned; it was apparently attacked and more than 30 women and children who sought refuge in its impressive tower kiva died horribly in the fire set to destroy the town (Stuart)

The Chacoan elites who held on in a half-dozen of the more stable great houses after this year lost access to nearly all their signature trade goods: corn surplus; dried meat; etc. [turquoise?] (Stuart)

The second Chaco drought was the coup de grace that brought the Chacoan culture down (Stuart)

Pochteca, “long-distance traders and spies who hailed from Aztec Mexico…we know them only from an era well after the AD 1300 abandonment, [though] they serve as a powerful model for hypothesized earlier traders who may have brought Mesoamerican ideas to the American Southwest, particularly Chaco Canyon.” (Roberts, p. 170)

Mimbres ended — at 1100 there were five to ten thousand people living in Mimbres towns throughout southwestern New Mexico; by 1150 there weren’t any (Lekson, p. 174)

When Chaco’s move to Aztec Ruins was complete, Mimbres region emptied (Lekson p. 241)

1130 to 1140

This decade, Bis sa’ani was built, perhaps to protect the central Chaco Canyon from unrest among the Chacoan northern farming communities (Stuart)

1130 to 1135

Chimney Rock abandoned

1130 to 1150s

Fighting peaked in the highland regions around Chaco Canyon (Stuart)

1130 to 1180

Prolonged drought with precipitation below normal — coincides with gradual abandonment of Chaco (Frazier p. 181, from Judge)

Ida Jean great house established (Stuart)

Kin Kletso construction began and continued through 1130 (NPS.gov)

Wallace great house established (Stuart)

After this date, the Anasazi center of gravity and gravitas shifted north, from Chaco Canyon to Aztec Ruins (Lekson, p. 153)

Construction at Chaco Canyon declined sharply and ceased by this year — just before the nasty drought of 1130-1180 (Lekson, p. 156)

1125 to 1129

Escalante great house established (Stuart)

1120

By this date, there was more than 100,000 square meters of floor area under roof in Chaco Canyon (Stuart)

The Anasazi were influenced most by neighboring Hohokam, Mogollon, and Mexican cultures. From Digging Into History, by Paul S. Martin

Most of the later and so-called higher developments of the Anasazi came to them from the Hohokam and Mogollon groups, so that the climax that occurred about A.D. 1100 may be regarded as an accumulations of southern and possibly Mexican traits that were taken over by the Anasazi bit by bit—by trade, by drift, perhaps by war—and reworked to fit their ideas and cultural layout. (Martin p. 20)

Anasazi Nazi-like culture stopped religious gatherings in Chaco, from Anasazi America: Seventeen Centuries on the Road from Center Place, by David E. Stuart

Large religious gatherings did not take place in Chaco Canyon after 1100. —Stuart/Anasazi America p. 143

Anasazi Nazi-like violence in 1100s, from Anasazi America: Seventeen Centuries on the Road from Center Place, by David E. Stuart

All of this evidence of violence dates to the 1100s. —Stuart/Anasazi America p. 121

Representations of masked dancers appear on Mogollon pottery (Martin p. 131)

Small copper trinkets, probably imported from Mexico, found in some Mogollon sites after this date (Martin p. 77)

After this date, large religious gatherings did not take place in Chaco Canyon (Stuart)

By this date there were nine great houses in Chaco Canyon: Peñasco Blanco, Casa Chiquita, Kin Kletso, Pueblo del Arroyo, Pueblo Bonito, Chetro Ketl, Hungo Pavi, Una Vida, and Wijiji; plus three up on the mesa: Pueblo Alto, New Alto, and Tsinkletzin (Stuart)

By this time, most of the great houses in the southern San Juan basic were abandoned (Stuart)

During the early part of this century, Chaco’s great houses walled their courtyards and built control gates where roadways passed village walls (Stuart)

Early this century, Wijiji constructed (NPS.gov)

Early this century evidence of violence abounds in and around Chaco Canyon (Stuart)

Early this century, a pit-house community in Gallina was laboriously stockaded, from fear of the invading Chacoan farmers; many such sites exist, all of which have been breached and burned (Stuart)

Early this century: An estimated 60 percent of adults and 38 percent of children died violently in the Gallina highlands after the collapse of Chacoan society (Stuart)

Early-to-mid-century: Kin ya’a (south of Chaco Canyon) was burned and abandoned (Stuart)

Huge explosion in number of kivas built (Stuart)

Kin ya’a was expanded (Stuart)

Peak population of Chacoans during early part of this decade (Frazier p. 91)

The center of Chaco culture shifted to near the banks of the San Juan River, north of Chaco Canyon the first few decades of this century (Stuart)

The middle of this century, Navajo people invaded Chacoan territory — perhaps the cause of the fear that made Chacoans build defensive structures and cliff dwellings (Stuart)

There are 3,200 known sites dated to this decade, a ninefold increase from 500 years before (Stuart)

Trafficking in Macaws began (presumably out of Mexico and into Four Corners area) — what’s the source on this? I propose Macaw feathers appeared long before this; need to double-check this one, or ignore it

Numic tribes (Utes, Paiutes, Shoshone–linguistic roots of the modern Hopi language) were in the Great Basin of Nevada as early as this date (Roberts p. 204, 205)

Pueblo towns such as Oraibi and Acoma began, perhaps even sooner (Lekson, p. 20)

Pueblo Bonito, originally build in the 900s with a solstitial alignment, changed and adopted Pueblo Alto’s consciously cardinal orientation (Lekson, p. 127)

1100 to 1130

Chaco rainfall in excess of normal (Frazier p. 203)

1100 to 1190

Most pit house communities were constructed and occupied in the highlands surrounding Chaco Canyon, most probably with farmers dispersed from the Red Mesa Valley and other areas sound of Chaco; most of these [if not all] were attacked and burned (Stuart)

1100 to 1300

Grand Gulch on Cedar Mesa in Utah inhabited again, the cliff dwellings were built, then abandoned (Roberts p. 131)

1100 to 1200s

Anasazi Nazi-like centralized control, from A History of the Ancient Southwest, by Stephen H. Lekson

Chaco…had a central government, however diffuse or non-Western…. It’s likely that Chaco had a regional economy. And perhaps Chaco and its successor, Aztec Ruins [in northern New Mexico], had the use of force; witness the brutality of apparently socially sanctioned events of the twelfth and thirteenth centuries. —Lekson p. 223

A.D. 1095-1100 were the most labor intensive. Chacoan construction programs took an average of 55,645 man-hours per year. —Page 179 From People of Chaco: A Canyon and Its Culture, by Kendrick Frazier

1095 to 1100

[Stephen] Lekson divided the construction activity into five-year segments and found that the last five years of the eleventh century, A.D. 1095-1100, were the most labor intensive. During those five years, Chacoan construction programs took up an average of 55,645 man-hours, or 5,565 man-days, or 186 man-months, per year. Thus thirty-one men working six months a year or sixty-two men working three months a year could have carried out the most intensive single period of construction at Chaco Canyon. —Page 179 (Frazier)

1088

Salmon ruin was mostly built as one massive project between A.D. 1088 and 1090. The great house was constructed in the shape of a square C. Its back (north) wall is 450 feet long. The two arms of the C, each 200 feet long, reach south toward the Great North Road from Chaco. The great house once stood two to four stories tall, contained at least 175 rooms, and had a floor area of 90,000 square feet—nearly two acres… [I]t was built in the midst of the worst drought since the rains had become more favorable 90 years before. —Anasazi America, by David E.

Solar dates in 1057 (Equinox and Solstice Calculator): Spring Equinox, March 14; Summer Solstice, June 15; Fall Equinox, September 17; Winter Solstice, December 15
Which dates would they watch the lunar standstill through the Chimney Rock twin towers? This illuminates (and surprises), from http://www.idialstars.com/mls.htm:

A major (or minor) lunar standstill always happens near an equinox; and what’s more, it happens when the Moon is at or near quarter phase. A major lunar standstill faithfully occurs within one week of a lunar or solar eclipse, and oftentimes takes place right between a lunar and solar eclipse.

This implies that the most likely date to watch a full moon rise between the twin spires of Chimney Rock National Monument, Colorado, closest to its standstill in 1057, is September 15.

Anasazi Timeline Crab Nebula July 4 10541054

July 4

Crab Nebula Supernova “first observed on 4 July 1054, and that lasted for a period of around two years. The event was recorded in contemporary Chinese astronomy, and references to it are also found in a later (13th-century) Japanese document, and in a document from the Arab world. Furthermore, there are a number of proposed, but doubtful, references from European sources recorded in the 15th century, and perhaps a pictograph associated with the Anasazi Pueblo Peoples found near the Peñasco Blanco site in New Mexico.” (Wikipedia article on SN 1054) Also “Around 4-5 July 1054 the supernova was visible in broad daylight, having reached a maximum brightness about ten times that of Venus, the brightest astronomical object visible from Earth besides the Sun and Moon. It remained visible by day for 23 days, and by night for 653 days.” (Solar Astronomy in the Prehistoric Southwest on the The National Center for Atmospheric Research site)

Kivas evolved as community houses, but the elite of Chaco Canyon co-opted them for private use. From

In many cases, Chaco elites were sometimes able to co-opt Great Kivas. The largest Great Kiva of its age was built within the walled plaza of Pueblo Bonito—the first and greatest Great House—about 1050. (Lekson p. 235)

A third masonry-lined kiva was added to site 627 (Stuart)

After this date, Chacoan farmers began moving into the northern San Juan basin with few, if any, underlying Basketmater or Pueblo I houses (Stuart)

Chacoans began construction in the early 900s at Penasco Blanco, Pueblo Bonito, and Una Vida. They gave them all remarkable similar floor plans. —Page 174 From People of Chaco: A Canyon and Its Culture, by Kendrick Frazier

Chacoans began construction in the early 900s at Penasco Blanco, Pueblo Bonito, and Una Vida…. They gave them all remarkable similar floor plans. They created a line of large circular pit structures in the plaza. Behind them they build a row of large ramada-living rooms, a second row of large featureless rooms, and in the rear, a third row of smaller storage rooms. They formed above-ground rectangular rooms into suites, each of which consisted of a ramada-living room, a large room, and paired storage rooms. This pattern of rooms is remarkably similar to smaller sites built in Chaco and in the surrounding area at the same time. —Pages 174-175 (Frazier) See Author Note The Anasazi Buildings of Chaco Canyon: Largest “Apartments” in the World.

By 900 there were hints of hierarchy . From A History of the Ancient Southwest, by Stephen H. Lekson

By 900 there were hints of hierarchy [in the Hohokam] not within but between towns, with the largest occupying positions of control at the heads of canal systems—positions of power. (Lekson)

Southerners [from Mexico, mainly the Toltecs]…entered the San Juan basin around A.D. 900 and found a suspicious but pliant population whom they terrorized into reproducing the theocratic lifestyle they had previously known in Mesoamerica. From Man Corn: Cannibalism and Violence in the Prehistoric American Southwest, by Christy G. Turner II

We propose that these southerners [from Mexico, mainly the Toltecs]…entered the San Juan basin around A.D. 900 and found a suspicious but pliant population whom they terrorized into reproducing the theocratic lifestyle they had previously known in Mesoamerica. This involved heavy payments of tribute, constructing the Chaco system of great houses and roads, and providing victims for ceremonial sacrifice. The Mexicans achieved their objectives through the use of warfare, violent example, and terrifying cult ceremonies that included human sacrifice and cannibalism. Turner/Man Corn pp. 482-483

Atlatl and snares had completely disappeared from Mogollon inventory (Martin, p. 75)

Anasazi Nazi-like ethnic hatred, from Anasazi America: Seventeen Centuries on the Road from Center Place, by David E. Stuart

As Chacoan society blossomed in the A.D. 900s and early 1000s, it probably incorporate several once-isolated tribal groups speaking different languages…. As Chacoan society came undone, those ancient linguistic, social, and religious differences would have been rich fodder for ethnic and tribal hatreds acted out in the uplands…[just as] Yugoslavia in the mid-1990s threw off…Tito’s nation and returned to medieval society. —Stuart/Anasazi America p. 143

Anasazi Nazis kept the peace for 300 years, from A History of the Ancient Southwest, by Stephen H. Lekson

Many things came to Chaco and stayed there, in the service of the kings. Maize moved into and through the canyon, from places that had plenty to places that had none. Consequently, violence and raiding almost ceased. Its success, from 900 to 1000, allowed Chaco’s leaders to expand their horizons. Its influence soon reached far beyond its original domain…. Local leaders almost everywhere on the Plateau joined with or deferred to Chaco…. From 900 to 1200, Chaco kept the peace, promoted the general welfare, enhanced its own glory, and got things done. —Lekson p. 235

Nearly every cannibalism site lay close to a Chaco outlier. And the dates were right—between 900 and 1200. From In Search of the Old Ones, by David Roberts.

One day in 1993, [physical anthropologist Christy G.] Turner and David Wilcox plotted the three dozen cannibalism sites on a large map. “Suddenly,” Turner recalled, “we had a kind of ‘Eureka!’ Nearly every site lay close to a Chaco outlier. And the dates were right—between 900 and 1200. Roberts/Old Ones, pp. 159-160

By 700 AD, Hohokam shell armlets were ubiquitous. From A History of the Ancient Southwest, by Stephen H. Lekson

People became Hohokam. Perhaps the most conspicuous and widespread markers of Hohokam were armlets of Glycimeris shell. Bivalve shells from the Gulf of California were carefully shaped into armlets and sometimes carved with symbols—birds carrying snakes, desert toads, and the like. Shell bracelets or armlets became a badge or marker of Hohokam; they had once been rarities, but after 700 they were ubiquitous. Someone in every sizable settlement had armlets prominently displayed on an upper arm. (Lekson)

Anasazi and Hohokam violence reached warfare levels by 850. From A History of the Ancient Southwest, by Stephen H. Lekson

Intervillage squabbles escalated after 700, occasionally reaching levels approaching warfare by 850. Increasing violence also called for leaders, military or diplomatic. (Lekson p. 233)

By 3,000 BC, 15,000 to 30,000 people lived in New Mexico. From Anasazi America: Seventeen Centuries on the Road from Center Place, by David E. Stuart

[By 3,000 B.C.,] we can guess that 15,000 to 30,000 souls lived in what is now New Mexico at any one moment, a stunning increase over the 2,000 to 6,000 probably tenants during the Paleo-Indian period [10,000 to 5,000 B.C.]. (Stuart/Anasazi America p. 20)

For 5,000 years, small bands of Clovis hunters and gatherers roamed the Southwest. From Anasazi America: Seventeen Centuries on the Road from Center Place, by David E. Stuart

For 5,000 years, from roughly 10,000 to 5,000 B.C., small bands of Clovis hunters and gatherers and their successors…roamed the Southwest. At the beginning of this period, in Clovis times, a cooler, wetter, late-Ice-Age climate prevailed. Giant game animals—among them mammoth, huge bison, camels, horses, and exotically horned elk—provided meat to supplement the small game and edible plants that these people sought in their ceaseless trek. (Stuart/Anasazi America p. 14)

The Paleo-Indian population of New Mexico from 10,000 to 5,000 BC was between 2,000 and 6,000 people. From Anasazi America: Seventeen Centuries on the Road from Center Place, by David E. Stuart

For the 5,000 years of the Paleo-Indian period [10,000 to 5,000 B.C.], population in what is now New Mexico probably fluctuated between 2,000 and 6,000 persons at any one time—a density of one person per 20 to 60 square miles. At these low population densities, technological and demographic change was agonizingly slow. Approximately one distinct new style of stone point for hunters’ lances and long darts was created every 500 years. It must have seemed a timeless world to those who spent whole lives on trek in small bands. (Stuart/Anasazi America p. 14-15)
