Part of an ancient Roman law code previously thought to have been lost forever has been discovered by researchers at University College London's Department of History. Simon Corcoran and Benet Salway made the breakthrough after piecing together 17 fragments of previously incomprehensible parchment.
The fragments were being studied at UCL as part of the Arts & Humanities Research Council-funded "Projet Volterra" -- a ten year study of Roman law in its full social, legal and political context.
Corcoran and Salway found that the text belonged to the Codex Gregorianus, or Gregorian Code, a collection of laws by emperors from Hadrian (AD 117-138) to Diocletian (AD 284-305), which was published circa AD 300. Little was known about the codex's original form and there were, until now, no known copies in existence.
"The fragments bear the text of a Latin work in a clear calligraphic script, perhaps dating as far back as AD 400," said Dr Salway. "It uses a number of abbreviations characteristic of legal texts and the presence of writing on both sides of the fragments indicates that they belong to a page or pages from a late antique codex book -- rather than a scroll or a lawyer's loose-leaf notes.
"The fragments contain a collection of responses by a series of Roman emperors to questions on legal matters submitted by members of the public," continued Dr Salway. "The responses are arranged chronologically and grouped into thematic chapters under highlighted headings, with corrections and readers' annotations between the lines. The notes show that this particular copy received intensive use."
The surviving fragments belong to sections on appeal procedures and the statute of limitations on an as yet unidentified matter. The content is consistent with what was already known about the Gregorian Code from quotations of it in other documents, but the fragments also contain new material that has not been seen in modern times.
"These fragments are the first direct evidence of the original version of the Gregorian Code," said Dr Corcoran. "Our preliminary study confirms that it was the pioneer of a long tradition that has extended down into the modern era and it is ultimately from the title of this work, and its companion volume the Codex Hermogenianus, that we use the term 'code' in the sense of 'legal rulings'."
This particular manuscript may originate from Constantinople (modern Istanbul) and it is hoped that further work on the script and on the ancient annotations will illuminate more of its history.

Last Neanderthals in Europe Died out 37,000 Years Ago
A paper by Professor João Zilhão and colleagues builds on his earlier research which proposed that, south of the Cantabro-Pyrenean mountain chain, Neanderthals survived for several millennia after being replaced or assimilated by anatomically modern humans everywhere else in Europe.
Although the reality of this 'Ebro Frontier' pattern has gained wide acceptance since it was first proposed by Professor Zilhão some twenty years ago, two important aspects of the model have remained the object of unresolved controversy: the exact duration of the frontier; and the causes underlying the eventual disappearance of those refugial Neanderthal populations (ecology and climate, or competition with modern human immigrants).
Professor Zilhão and colleagues now report new dating evidence for the Late Aurignacian of Portugal, an archaeological culture unquestionably associated with modern humans, that firmly constrains the age of the last Neanderthals of southern and western Iberia to no younger than some 37,000 years ago.
This new evidence therefore puts at five millennia the duration of the Iberian Neanderthal refugium, and counters speculations that Neanderthal populations could have remained in the Gibraltar area until 28,000 years ago.
These findings have important implications for the understanding of the archaic features found in the anatomy of a 30,000 year old child unearthed at Lagar Velho, Portugal. With the last of the Iberian Neanderthals dating to many millennia before the child was born, 'freak' crossbreeding between immediate ancestors drawn from distinct 'modern' and 'Neanderthal' gene pools cannot be a viable explanation. The skeleton's archaic features must therefore represent evolutionarily significant admixture at the time of contact, as suggested by the team who excavated and studied the fossil.
Professor Zilhão said: "I believe the 'Ebro frontier' pattern was generated by both climatic and demographic factors, as it coincides with a period of globally milder climate during which oak and pine woodlands expanded significantly along the west façade of Iberia.
"Population decrease and a break-up of interaction networks probably occurred as a result of the expansion of such tree-covered landscapes, favouring the creation and persistence of population refugia.
"Then, as environments opened up again for large herbivore herds and their hunters as a result of the return to colder conditions, interaction and movement across the previous boundary must have ensued, and the last of the Neanderthals underwent the same processes of assimilation or replacement that underpin their demise elsewhere in Europe five millennia earlier."
The dating was undertaken by experts at the University of Vienna (VERA laboratory) led by Professor Eva Maria Wild, and at the University of Oxford's Radiocarbon Accelerator Unit.
Professor Wild, head of the 14C program at VERA (Vienna Environmental Research Accelerator) said: "Accurate 14C dating was crucial for this study. For layer 2 of the cave sediment we achieved this by selecting teeth for 14C dating and by comparing the 14C results of the same sample after different, elaborate sample pre-treatments. Agreement between the results obtained with different methods provides a proof for accurate dating."

Remains of a building in Tel Aviv 8.000 years old
Remains of a prehistoric building, the earliest ever discovered in the Tel Aviv region and estimated to be between 7,800 and 8,400 years old, were recently discovered in an archaeological excavation in Ramat Aviv.
Ancient artifacts thought to be 13,000 and 100,000 years old were also discovered there.
Archaeologist Ayelet Dayan, director of the excavation on behalf of the Israel Antiquities Authority, said that "this discovery is both important and surprising to researchers of the period. For the first time we have encountered evidence of a permanent habitation that existed in the Tel Aviv region 8,000 years ago."
"The site is located on the northern bank of the Yarkon River, not far from the confluence with Nahal Ayalon. We can assume that this fact influenced the ancient settlers in choosing a place to live. The fertile alluvium soil along the fringes of the streams was considered a preferred location for a settlement in ancient periods," she said.
During the Neolithic period (also known as the New Stone Age) man went from a nomadic existence of hunting and gathering to living in permanent settlements and began to engage in agriculture.
Remains of an ancient building with at least three rooms were discovered at the site. The pottery shards that were found there attest to the age of the site, which dates to the Neolithic period. In addition, flint tools such as sickle blades were discovered, as well as numerous flakes left over from the knapping of these implements, which are indicative of an ancient tool-making industry.
Flint implements that are also ascribed to earlier periods were discovered at the site: a point of a hunting tool from the Middle Paleolithic period and items that date to c. 13,000 years ago.
Other interesting finds were also uncovered in the excavation, among them a fragment of a base of a basalt bowl and animal remains - hippopotamus bones and teeth that probably belonged to sheep or goat.

Most British men are descended from ancient farmers
Farming in the blood: More than 60% of British men have a Y chromosome that dates back to the origin of agriculture. Photograph: Howard Sochurek/Rex Features
Most men in Britain are descended from the first farmers to migrate across Europe from the Near East 10,000 years ago, scientists say.
Ancient farmers left their genetic mark on modern males by breeding more successfully than indigenous hunter-gatherer men as they made their way west, a study has found.
As a result, more than 60% of British men, and nearly all of those in Ireland, can trace their Y chromosome back to the agricultural revolution, or more precisely the sexual success of the men behind it.
The farmers' Y chromosome becomes more common in the west of England and reaches a national peak of 78% in Cornwall, scientists found.
Men with surnames including Titchmarsh and Haythornthwaite are among the most likely to carry the farmers' Y chromosome, known as R1b1b2. The Y chromosome is passed down the male line only, from father to son.
"These farmers expanded into territories with small and sparse hunter-gather populations and moved on as time passed. The Y chromosome got caught up in that and it surfed the wave of expansion," said Mark Jobling, a geneticist at Leicester University and an author of the study.
The rise of farming is one of the most important cultural transformations in the history of modern humans. Increased food production allowed communities to settle rather than wander in search for food, a shift that heralded the huge expansion of the human population.
The first European farmers came from the "fertile crescent" that stretched from the eastern Mediterranean to the Persian Gulf, but experts have argued whether the westerly spread of agriculture was driven by the cultural transmission of ideas and technology, or by migrating farmers.
Researchers led by Jobling collected DNA samples from more than 2,500 men across Europe. Around 80% of the men had the R1b1b2 type of Y chromosome, making it the most common lineage on the continent.
A map showing the distribution of the chromosome across Britain reveals that it became increasingly common but less genetically diverse from the south east to the north west. The analysis, published in the journal PLoS Biology, suggests the R1b1b2 Y chromosome entered the country with the earliest farmers in the south east and gradually spread west as they migrated.
Genetic tests on women showed that most are descendants of hunter-gatherer females. "To us, this suggests a reproductive advantage for farming males over indigenous hunter-gatherer males during the switch from hunting and gathering to farming," said Patricia Balaresque, a co-author of the study.
"Maybe back then, it was just sexier to be a farmer."

Pashtuns The Lost Tribes?
Israel is to fund a rare genetic study to determine whether there is a link between the lost tribes of Israel and the Pashtuns of Afghanistan and northern Pakistan.
Historical and anecdotal evidence strongly suggests a connection, but definitive scientific proof has never been found. Some leading Israeli anthropologists believe that, of all the many groups in the world who claim a connection to the 10 lost tribes, the Pashtuns, or Pathans, have the most compelling case. Paradoxically it is from the Pashtuns that the ultra-conservative Islamic Taliban movement in Afghanistan emerged. Pashtuns themselves sometimes talk of their Israelite connection, but show few signs of sympathy with, or any wish to migrate to, the modern Israeli state.
Now an Indian researcher has collected blood samples from members of the Afridi tribe of Pashtuns who today live in Malihabad, near Lucknow, in northern India. Shahnaz Ali, from the National Institute of Immunohaematology in Mumbai, is to spend several months studying her findings at Technion, the Israel Institute of Technology, in Haifa. A previous genetic study in the same area did not provide proof one way or the other.
The Assyrians conquered the kingdom of Israel some 2,730 years ago, scattering 10 of the 12 tribes into exile, supposedly beyond the mythical Sambation river. The two remaining tribes, Benjamin and Judah, became the modern-day Jewish people, according to Jewish history, and the search for the lost tribes has continued ever since. Some have claimed to have found traces of them in modern day China, Burma, Nigeria, Central Asia, Ethiopia and even in the West.
But it is believed that the tribes were dispersed in an area around modern-day northern Iraq and Afghanistan, which makes the Pashtun connection the strongest.
"Of all the groups, there is more convincing evidence about the Pathans than anybody else, but the Pathans are the ones who would reject Israel most ferociously. That is the sweet irony," said Shalva Weil, an anthropologist and senior researcher at the Hebrew University of Jerusalem.
The Pashtuns have a proud oral history that talks of descending from the Israelites.
Their tribal groupings have similar names, including Yusufzai, which means sons of Joseph; and Afridi, thought by some to come from Ephraim. Some customs and practices are said to be similar to Jewish traditions: lighting candles on the sabbath, refraining from eating certain foods, using a canopy during a wedding ceremony and some similarities in garments.
Weil cautioned, however, that this is not proof of any genetic connection. DNA might be able to determine which area of the world the Pashtuns originated from, but it is not at all certain that it could identify a specific genetic link to the Jewish people.
So far Shahnaz Ali has been cautious. "The theory has been a matter of curiosity since long ago, and now I hope a scientific analysis will provide us with some answers about the Israelite origin of Afridi Pathans. We still don't know what the truth is, but efforts will certainly give us a direction," she told the Times of India last year.
Some are more certain, among them Navras Aafreedi, an academic at Luck now University, himself a Pashtun from the Afridi tribe. His family trace their roots back to Pathans from the Khyber Agency of what is today north-west Pakistan, but he believes they stretch back further to the tribe of Ephraim.
"Pathans, or Pashtuns, are the only people in the world whose probable descent from the lost tribes of Israel finds mention in a number of texts from the 10th century to the present day, written by Jewish, Christian and Muslim scholars alike, both religious as well as secularists," Aafreedi said.
The implications of any find are uncertain. Other groups that claim Israelite descent, including those known as the Bnei Menashe in India and some in Ethiopia, have migrated to Israel. That is unlikely with the Pashtuns.
But Weil said the work was absorbing, well beyond questions of immigration. "I find a myth that has been so persistent for so long, for 2,000 years, really fascinating," she said.

Were The Hebrews Slaves in Egypt?
Worker tombs suggest pyramids not built by slaves
Tombs of workers who built the pyramids of Khufu and Khafre in Giza support the view that the Great Pyramids were built by free workers and not slaves, as widely believed, Egypt's chief archaeologist said on Sunday.
"These tombs were built beside the king's pyramid, which indicates that these people were not by any means slaves," Zahi Hawass, the chief archaeologist heading the Egyptian excavation team, said in a statement.
"If they were slaves, they would not have been able to build their tombs beside their king's."
Hawass had earlier found graffiti on the walls from workers calling themselves "friends of Khufu" -- another sign that they were not slaves.
The tombs, on the Giza plateau on the western edge of Cairo, are 4,510 years old and lie at the entrance of a one-km (half mile)-long necropolis.
Hawass said evidence had been found showing that farmers in the Delta and Upper Egypt had sent 21 buffalo and 23 sheep to the plateau every day to feed the builders, believed to number around 10,000 -- or about a tenth of Greek historian Herodotus's estimate of 100,000.
These farmers were exempted from paying taxes to the government of ancient Egypt -- evidence that he said underscored the fact they were participating in a national project.

Neanderthal mind capable of advanced thought
Use of body ornamentation shows Neanderthal mind capable of advanced thought
The widespread view of Neanderthals as cognitively inferior to early modern humans is challenged by new research from the University of Bristol published today in Proceedings of the National Academy of Sciences.
Professor João Zilhão and colleagues examined pigment-stained and perforated marine shells, most certainly used as neck pendants, from two Neanderthal-associated sites in the Murcia province of south-east Spain (Cueva de los Aviones and Cueva Antón). The analysis of lumps of red and yellow pigments found alongside suggest they were used in cosmetics. The practice of body ornamentation is widely accepted by archaeologists as conclusive evidence for modern behaviour and symbolic thinking among early modern humans but has not been recognised in Neanderthals – until now.
Professor Zilhão said: "This is the first secure evidence that, some 50,000 years ago – ten millennia before modern humans are first recorded in Europe – the behaviour of Neanderthals was symbolically organised."
A Spondylus gaederopus shell from the same site contained residues of a reddish pigmentatious mass made of lepidocrocite mixed with ground bits of hematite and pyrite (which, when fresh, have a brilliant black, reflective appearance), suggesting the kind of inclusion 'for effect' that one would expect in a cosmetic preparation.
The choice of a Spondylus shell as the container for such a complex recipe may relate to the attention-grabbing crimson, red, or violet colour and exuberant sculpture of these shells, which have led to their symbolic- or ritual-related collection in a variety of archaeological contexts worldwide.
A concentration of lumps of yellow colorant from Cueva de los Aviones (most certainly the contents of a purse made of skin or other perishable material) was found to be pure natrojarosite – an iron mineral used as a cosmetic in Ancient Egypt.
While functionally similar material has been found at Neanderthal-associated sites before, it has been explained by stratigraphic mixing (which can lead to confusion about the dating of particular artefacts), Neanderthal scavenging of abandoned modern human sites, or Neanderthal imitation without understanding of behaviours observed among contemporary modern human groups.
For example, controversy has surrounded the perforated and grooved teeth and decorated bone awls found in the Châtelperronian culture of France. In earlier work, Professor Zilhão and colleagues have argued they are genuine Neanderthal artefacts which demonstrate the independent evolution of advanced cognition in the Neanderthal lineage.
However, the Châtelperronian evidence dates from 40,000 to 45,000 years ago, thus overlapping with the period when anatomically modern human people began to disperse into Europe (between 40,000 and 42,000 years ago) and leaving open the possibility that these symbolic artifacts relate, in fact, to them.
Professor Zilhão said: "The evidence from the Murcian sites removes the last clouds of uncertainty concerning the modernity of the behaviour and cognition of the last Neanderthals and, by implication, shows that there is no reason any more to continue to question the Neanderthal authorship of the symbolic artefacts of the Châtelperronian culture.
"When considering the nature of the cultural and genetic exchanges that occurred between Neanderthals and modern humans at the time of contact in Europe, we should recognise that identical levels of cultural achievement had been reached by both sides."
Accurate radiocarbon dating of shell and charcoal samples from Cueva de los Aviones and Cueva Antón was crucial to the research. The dating was undertaken at the University of Oxford's Radiocarbon Accelerator Unit.
Dr Thomas Higham, Deputy Director of the Radiocarbon Unit in the School of Archaeology said: "Dating samples that approach the limit of the technique, at around 55,000 years before present, is a huge challenge. We used the most refined methods of pre-treatment chemistry to obtain accurate dates for the sites involved by removing small amounts of more modern carbon contamination to discover that the shells and charcoal samples were as early as 50,000 years ago."

Ancient Hebrew Text Revolutionizes Bible Origins
*
Most ancient Hebrew biblical inscription deciphered
A breakthrough in the research of the Hebrew scriptures has shed new light on the period in which the Bible was written. Prof. Gershon Galil of the Department of Biblical Studies at the University of Haifa has deciphered an inscription dating from the 10th century BCE (the period of King David's reign), and has shown that this is a Hebrew inscription.

The significance of this breakthrough it shows that at least some of the bible could have been written hundreds of years before the dates presented today in research and that the Kingdom of Israel already existed at that time.
The inscription itself, which was written in ink on a 15 cm X 16.5 cm trapezoid pottery shard, was discovered a year and a half ago at excavations that were carried out by Prof. Yosef Garfinkel at Khirbet Qeiyafa near the Elah valley. The inscription was dated back to the 10th century BCE, which was the period of King David's reign, but the question of the language used in this inscription remained unanswered, making it impossible to prove whether it was in fact Hebrew or another local language.

Prof. Galil's deciphering of the ancient writing testifies to its being Hebrew, based on the use of verbs particular to the Hebrew language, and content specific to Hebrew culture and not adopted by any other cultures in the region. "This text is a social statement, relating to slaves, widows and orphans. It uses verbs that were characteristic of Hebrew, such as asah ("did") and avad ("worked"), which were rarely used in other regional languages. Particular words that appear in the text, such as almanah ("widow") are specific to Hebrew and are written differently in other local languages. The content itself was also unfamiliar to all the cultures in the region besides the Hebrew society: The present inscription provides social elements similar to those found in the biblical prophecies and very different from prophecies written by other cultures postulating glorification of the gods and taking care of their physical needs," Prof. Galil explains.
The inscription is the earliest Hebrew inscription to be found, testifying to Hebrew writing abilities as early as the 10th century BCE. This stands opposed to the dating of the composition of the Bible in current research, which would not have recognized the possibility that the Bible or parts of it could have been written during this ancient period.
Prof. Galil also notes that the inscription was discovered in a provincial town in Judea. He explains that if there were scribes in the periphery, it can be assumed that those inhabiting the central region and Jerusalem were even more proficient writers. "It can now be maintained that it was highly reasonable that during the 10th century BCE, during the reign of King David, there were scribes in Israel who were able to write literary texts and complex historiographies such as the books of Judges and Samuel." He adds that the complexity of the text discovered in Khirbet Qeiyafa, along with the impressive fortifications revealed at the site, refute the claims denying the existence of the Kingdom of Israel at that time.
The contents of the text express social sensitivity to the fragile position of weaker members of society. The inscription testifies to the presence of strangers within the Israeli society as far back as this ancient period, and calls to provide support for these strangers. It appeals to care for the widows and orphans and that the king – who at that time had the responsibility of curbing social inequality - be involved. This inscription is similar in its content to biblical scriptures (Isaiah 1:17, Psalms 72:3, Exodus 23:3, and others), but it is clear that it is not copied from any biblical text.
English translaton of the deciphered text:
1' you shall not do [it], but worship the [Lord].
2' Judge the sla[ve] and the wid[ow] / Judge the orph[an]
3' [and] the stranger. [Pl]ead for the infant / plead for the po[or and]

Dead Sea Scrolls Authorship In Dispute
The Dead Sea Scrolls—comprising more than 800 documents made of animal skin, papyrus and even forged copper—deepened our understanding of the Bible and shed light on the histories of Judaism and Christianity. Among the texts are parts of every book of the Hebrew canon—what Christians call the Old Testament—except the book of Esther. The scrolls also contain a collection of previously unknown hymns, prayers, commentaries, mystical formulas and the earliest version of the Ten Commandments. Most were written between 200 B.C. and the period prior to the failed Jewish revolt to gain political and religious independence from Rome that lasted from A.D. 66 to 70—predating by 8 to 11 centuries the oldest previously known Hebrew text of the Jewish Bible.
Tour guides shepherding the tourists through the modest desert ruins speak of the scrolls’ origin, a narrative that has been repeated almost since they were discovered more than 60 years ago. Qumran, the guides say, was home to a community of Jewish ascetics called the Essenes, who devoted their lives to writing and preserving sacred texts. They were hard at work by the time Jesus began preaching; ultimately they stored the scrolls in 11 caves before Romans destroyed their settlement in A.D. 68.
But hearing the dramatic recitation, Peleg, 40, rolls his eyes. “There is no connection to the Essenes at this site,” he tells me as a hawk circles above in the warming air. He says the scrolls had nothing to do with the settlement. Evidence for a religious community here, he says, is unconvincing. He believes, rather, that Jews fleeing the Roman rampage hurriedly stuffed the documents into the Qumran caves for safekeeping. After digging at the site for ten years, he also believes that Qumran was originally a fort designed to protect a growing Jewish population from threats to the east. Later, it was converted into a pottery factory to serve nearby towns like Jericho, he says.
Other scholars describe Qumran variously as a manor house, a perfume manufacturing center and even a tannery. Despite decades of excavations and careful analysis, there is no consensus about who lived there—and, consequently, no consensus about who actually wrote the Dead Sea Scrolls.
“It’s an enigmatic and confusing site,” acknowledges Risa Levitt Kohn, who in 2007 curated an exhibit about the Dead Sea Scrolls in San Diego. She says the sheer breadth and age of the writings—during a period that intersects with the life of Jesus and the destruction of the Second Jewish Temple in Jerusalem—make Qumran “a powder keg” among normally placid scholars. Qumran has prompted bitter feuds and even a recent criminal investigation.
Nobody doubts the scrolls’ authenticity, but the question of authorship has implications for understanding the history of both Judaism and Christianity. In 164 B.C., a group of Jewish dissidents, the Maccabees, overthrew the Seleucid Empire that then ruled Judea. The Maccabees established an independent kingdom and, in so doing, tossed out the priestly class that had controlled the temple in Jerusalem since the time of King Solomon. The turmoil led to the emergence of several rival sects, each one vying for dominance. If the Qumran texts were written by one such sect, the scrolls “help us to understand the forces that operated after the Maccabean Revolt and how various Jewish groups reacted to those forces,” says New York University professor of Jewish and Hebraic studies Lawrence Schiffman in his book Reclaiming the Dead Sea Scrolls. “While some sects were accommodating themselves to the new order in various ways, the Dead Sea group decided it had to leave Jerusalem altogether in order to continue its unique way of life.”
And if Qumran indeed housed religious ascetics who turned their backs on what they saw as Jerusalem’s decadence, then the Essenes may well represent a previously unknown link between Judaism and Christianity. “John the Baptizer, Jesus’ teacher, probably learned from the Qumran Essenes—though he was no Essene,” says James Charlesworth, a scrolls scholar at Princeton Theological Seminary. Charlesworth adds that the scrolls “disclose the context of Jesus’ life and message.” Moreover, the beliefs and practices of the Qumran Essenes as described in the scrolls—vows of poverty, baptismal rituals and communal meals—mirror those of early Christians. As such, some see Qumran as the first Christian monastery, the cradle of an emerging faith.

Jesus-era Home Found In Nazareth
*
Archaeologists in Israel say they have uncovered the remains of the first dwelling in Nazareth believed to date back to the time of Jesus Christ.
The discovery sheds light on how people lived 2,000 years ago, when Christians believe Jesus was growing up there, Israel's Antiquities Authority said.
A spokeswoman said Jesus and his childhood friends likely knew the home.
It was found near the place where angel Gabriel is believed to have told Mary that she would give birth to Jesus.
The archaeologists found the remains of a wall, a hideout, and a cistern for collecting rain water.
"The building that we found is small and modest and it is most likely typical of the dwellings in Nazareth in that period," said Yardenna Alexandre of the Antiquities Authority, who directed the dig.
She said the 1st Century home, near the present-day Church of the Annunciation, is believed to have housed a "simple Jewish family" in two rooms and courtyard.
She described Nazareth, now Israel's largest Arab city with a population of 65,000 people, as a "small hamlet" during the time of Jesus.
The discovery was made when builders dug up the courtyard of a former convent to make room for a new Christian centre.
The dwelling will now become a part of the new centre, which is being built by the French Roman Catholic group, Chemin Neuf.

The Oldest Business in North America
The Miwok Tribe conducted perhaps the oldest business in North America.
Long before textiles were produced en masse or Andrew Carnegie perfected steel manufacturing, this ancient group of Native Americans was manufacturing and trading salt. New research from the USGS reveals that hundreds of man-made basins three to four feet in diameter were carved into solid granite and cover an area the size of a football field in the Sierra Nevada. These basins were filled with water from a nearby salt spring. When the water evaporated in the hot summer months, a salt residue that could be harvested was left at the bottom. They could manufacture three tons of salt each season, giving them more than enough for use within their own community and a surplus for trade.
Full report:
Hand-Hewn Granite Basins at Native American Saltworks, Sierra Nevada, California
This site in the northern Sierra Nevada contains about 369 circular basins carved in fresh, glaciated granodioritic bedrock, with 325 basins crowded together in an area of 2,700 m2 on the main terrace. These terrace basins have a median average diameter of 125 cm (80 percent between 100 and 160 cm) and a median depth of 75–80 cm. They show a strong congruity to similar granitic basins in the southern Sierra Nevada apparently of Native American origin that are generally shallower.
The basins are not of natural origin, as indicated by uniformity in size and nonoverlapping character of the basins; their common arrangement in lineaments; details of the shape of the basins; features in common with granite basins in the Southern Sierra Nevada; and, most compelling, the clustering of all the basins adjacent to (within 20 m of) two saline streams fed from a nearby salt spring. Native Americans apparently excavated them for the purpose of collecting saline water to evaporate and make salt for their use, and also as an animal attractant and a trade commodity.
The flow of the salty streams delivers about 2.9 metric tons of salt per summer season to the basin area, and evaporation rates and the holding capacity of the basins indicate that about 2.5 tons of salt could be produced per season. This correspondence shows that the Indians made enough basins to exploit the resource. The site is the most impressive prehistoric saltworks yet discovered in North America and represents a unique departure from traditional hunter-gatherer activities to that of manufacturing.
The actual grinding of so many basins in granite could not have been done without the labor of a concentrated population. It is believed that the work was accomplished over a long time by many people and with the use of fire to help disaggregate the bedrock.
