Zaña Valley is a designated archaeological area in northern Peru . The valley is located southeast of the city of Chiclayo . The Zaña River is often dry in its lower course, but occasionally has torrential flows. The city of Zaña is the principal settlement in the valley. The valley contains the earliest known canals in South America . These engineering belongs to a preceramic period and consists of small stone-lined canals that drew water from uphill streams in the Andes Mountains . Accelerator Mass Spectrometer dating of aggregate flecks of charcoal from the oldest canal was to 6705 + 75 14C. Archaeologists believe that the canals were used as early as 6,700 and 4,500 years ago. A temple associated with more than one cultural period also has been discovered in the valley.

22-402: Tom Dillehay and his archaeological team from Vanderbilt University discovered canals in 1989 that are confirmed to be approximately 5,400 years old, but the importance of the canals has been uncovered only in more recent field study. The placement and slope of the canals demonstrates engineering planning. The canals were more or less u-shaped, symmetrical, and shallow. Stones lining the sides of

44-511: A 'water cult', abandoned around 250 BC. One of the tombs was associated with the Formative period. It contained an adult male and a ceramic bottle with two spouts and a bridge handle. Later, the site was used as a burial ground by the Chumy people and twenty tombs belonging to the people of Chumy were discovered. Excavations revealed that as many as three construction phases took place in the building of

66-687: A huge mound of ash, stones, textiles, plants and shells, with some burials and constructions. It was first excavated by Junius B. Bird in 1946–1947 who excavated three large test pits in or beside it. The remains, now at the American Museum of Natural History in New York City, include many examples of complex textiles made with twining techniques which incorporated intricate designs of mythological humans, condors, snakes and crabs. The many stone artifacts were not fancy—fish net weights, flakes and simple pebble tools; there were no projectile points. In

88-647: Is Tibitó , in the mountains of Colombia, which has been carbon dated to 11,740 BP. Monte Verde II in southern Chile, dating 14,000 cal BP or earlier, is also predominantly unifacial. In North America, early unifacial assemblages are quite commonly found along with bifacial assemblages. Such sites as Gault and the nearby Friedkin sites in Texas, Cactus Hill in Virginia, and Paisley Cave in Oregon are notable. All of them are also dated before 14,000 cal BP. Until recently, it

Huaca Prieta Huaca Prieta is the site of a prehistoric settlement beside the Pacific Ocean in the Chicama Valley , just north of Trujillo , La Libertad Province , Peru . It is a part of the El Brujo Archaeological Complex, which also includes Moche (culture) sites. Huaca Prieta was occupied as early as 14,500 BP , long before ceramics were introduced. It consists of

He has previously held teaching positions at the Universidad Austral de Chile and the University of Kentucky . Dillehay received his advanced degrees in anthropology from the University of Texas at Austin. He established anthropology departments at

154-517: Is the earliest maize discovered so far in South America. According to archaeologist Tom D. Dillehay , several varieties of early corn have been discovered here. "Most notably, Dillehay’s team found the world’s earliest-known collection of corn macroremains (e.g., stalks and cobs), which included all early varieties of the plant—ceremonial popcorn, corn used for chicha beer, flour corn, and corn for foraging animals." This suggests that Huaca Prieta

176-587: The Field Museum , Chicago under the leadership of Luis Muro Ynoñán discovered a 4,000-year-old temple at La Otra Banda site in the Saña district . The temple walls were decorated with intricate images of figures with human bodies, bird heads, and reptilian claws. Skeletal remains of three adults were found. 6°56′03″S 79°36′52″W  /  6.9341°S 79.6145°W  / -6.9341; -79.6145 Tom Dillehay Tom Dalton Dillehay (born 1948/1949)

198-502: The first humans arrived in the Americas around 15,000 years ago, challenges the "Clovis first" paradigm by indicating the possibility of an earlier human presence in South America. This proposal based on his research at Monte Verde met with virulent resistance within the field of archaeology, but was ultimately accepted two decades later. Dillehay's work combines archaeology and ethnography. His excavations span eight countries, including

220-682: The Guañape, Early Cupisnique and Cupisnique cultures. The last is linked to the highland Chavín culture . A large tsunami damaged both mounds leaving a thick layer of cobblestones just north of the preceramic mound, at about 850 BCE, between the two Cupisnique phases. The end of Huaca Prieta's occupation came gradually. It fell into disuse as the economy changed to being more agriculture-based, and its ceremonial significance diminished. Other nearby mounds supplanted Huaca Prieta in importance, such as Paredones and El Brujo. The earliest occupational levels of Huaca Prieta have been examined in 2017. These are

242-522: The Old World as they rely on gravity to draw water over short distances, where it could be easily managed much like the canals in Pharaonic Egypt or the kingdoms of Mesopotamia. This allowed for a connection and communication within the community, as the responsibilities were shared amongst everyone. Dillehay states that he does not believe there was a central leader directing the building of these canals as

264-636: The Pontifical Catholic University of Chile in Temuco and at Austral University of Chile in Valdivia. In 1977, Dillehay became involved in the excavations at Monte Verde , a site in Chile where an early human settlement was discovered in 1975. Based on calibrated carbon 14 dates, Dillehay proposed that the remains found at Monte Verde are approximately 14,800 years old. This evidence, which suggests that

286-728: The Siches area (in north Peru, close to the Ecuador border), share similar developments as Huaca Prieta. The Itaparica tradition in central-northwestern Brazil, dated between 11,000 and 10,000 BP, is believed to be totally unifacial. It is associated with a rapid population density increase in Brazil at that time. The San Dieguito complex of Southern California, the Southwestern United States , and northwestern Mexico (as early as 10,200 BP) also featured predominantly unifaces. Also relevant

308-791: The United States. Dillehay began excavating Huaca Prieta in 2007, where he found evidence that people had lived in that area between 13,300 and 14,200 years ago. In addition to his archaeological work, Dillehay has conducted ethnographic research among the Mapuche people of southern Chile and the Jívaro community in northern Peru . His primary interest is exploring how ancient groups of foragers transitioned into settled societies. Dillehay has published 32 books. As of 2024, he lives in Santa Fe, New Mexico.

330-506: The building of these cananls was during the very early stages of the Andean Society when organization of the surrounding areas shows no signs of social hierarchy . In November 2019, Peruvian archaeologists led by Walter Alva discovered a 3,000-year-old, 130 feet long megalithic temple with 21 tombs in the Oyotún district of the valley. They initially interpreted the temple as an artifact of

352-444: The canals are thought to have been used to protect against erosion. The canals range in size and are all built to rely on gravity to draw water downward, from an upper canal to crops below. The upkeep for these canals also reveals social organization of labor. The construction and maintenance of these canals required a lot of work from the entire community. Dillehay states that the engineering of these canals compares to early canals in

374-478: The levels dated to 15,000-8000 BP. They indicate only an occasional and intermittent human presence before the ceremonial mound was built. The stone artifacts are characterised by minimally worked unifacial stone tools . Such tools are also characteristic of some other similarly dated sites in South America. The absence of fishhooks and harpoons has also been noted at these levels. It is likely that those early occupants engaged primarily in simple food gathering along

396-484: The shoreline, as well as in trapping and clubbing abundant local species of animals. Bifacial stone tools or projectile points were absent in those levels. According to the authors, Several other sites in the Americas featuring only unifacial stone tools at early occupational levels are also known. In particular, the Amotape complex of the northern coast of Peru (9,000-7,100 BCE) is notable. This cultural complex, as well as

418-494: The temple. The first phase was between 1500 BC-800 BC when people built the foundations of the building from cone-shaped clay. The second phase was between 800 BC-400 BC when the megalithic temple was built under the influence of the pre-Inca civilization known as the Chavín culture . Finally, a third phase was during 400 BC-100 BC when people added circular pillars used to hold up the roof of the temple. In June 2024, archaeologists from

440-478: The upper part of the mound there were many underground structures of unknown function, some with burials. They were made of cobblestones cemented with an ash-water mixture. The inhabitants fished, gathered shellfish, and grew fruit, gourds, squash, peppers, beans, tubers and, importantly, cotton. There is a low mound 70–170 m to the north (now called Monticulo Cupisnique) where Bird excavated three test pits. He found many ruins and much refuse, including ceramics of

462-420: Was an important hub in a large trading network reaching all the way to Mexico, where domesticated corn originated. A team of scientists excavating Huaca Prieta between 2007 and 2013 also discovered evidence of the avocado dating back perhaps 15,000 years. It had been thought previously that the avocado originated in the area of Puebla, Mexico, some 8,000 years ago. In 2016, 6000-year-old dyed cotton fabric

484-522: Was believed that maize was introduced to the region rather late, after the tsunami. In 2012, it was reported that corncobs found at two ancient sites in Peru (Paredones and Huaca Prieta) may date from as early as 4700   BCE. This suggests that people living along the coast of northern Peru were already eating corn by that time. These results were reported by Dolores Piperno , and other scientists from Washington's National Museum of Natural History . This
