Clovis points are the characteristically fluted projectile points associated with the New World Clovis culture, a prehistoric Paleo-American culture. They are present in dense concentrations across much of North America and they are largely restricted to the north of South America. There are slight differences in points found in the Eastern United States bringing them to sometimes be called "Clovis-like". Clovis points date to the Early Paleoindian period, with all known points dating from roughly 13,500 to 12,800 years ago. Clovis fluted points are named after the city of Clovis, New Mexico, where examples were first found in 1929 by Ridgely Whiteman.
The Clovis culture is a prehistoric Paleoamerican culture, named for distinct stone and bone tools found in close association with Pleistocene fauna, particularly two mammoths, at Blackwater Locality No. 1 near Clovis, New Mexico, in 1936 and 1937. It appears around 11,500–11,000 uncalibrated years before present (YBP) at the end of the last glacial period and is characterized by the manufacture of "Clovis points" and distinctive bone and ivory tools. Archaeologists' most precise determinations at present suggest this radiocarbon age is equal to roughly 13,200 to 12,900 calendar years ago.
The Columbian mammoth is an extinct species of mammoth that inhabited the Americas as far north as the Northern United States and as far south as Costa Rica during the Pleistocene epoch. It was one of the last in a line of mammoth species, beginning with Mammuthus subplanifrons in the early Pliocene. DNA studies show that the Columbian mammoth was a hybrid species between woolly mammoths and another lineage descended from steppe mammoths; the hybridization happened more than 420,000 years ago. The pygmy mammoths of the Channel Islands of California evolved from Columbian mammoths. The closest extant relative of the Columbian and other mammoths is the Asian elephant.
Lubbock Lake Landmark, also known as Lubbock Lake Site, is an important archeological site and natural history preserve in the city of Lubbock, Texas. The preserve is 336 acres and is a protected state and federal landmark. There is evidence of ancient people and extinct animals at Lubbock Lake Landmark. It has evidence of nearly 12,000 years of use by ancient cultures on the Llano Estacado. It is part of the Museum of Texas Tech University.
Emil Walter "Doc" Haury was an influential archaeologist who specialized in the archaeology of the American Southwest. He is most famous for his work at Snaketown, a Hohokam site in Arizona.
The Younger Dryas impact hypothesis (YDIH) or Clovis comet hypothesis is a speculative attempt to explain the onset of the Younger Dryas (YD) as an alternative to the long standing and widely accepted cause due to a significant reduction or shutdown of the North Atlantic "Conveyor" in response to a sudden influx of fresh water from Lake Agassiz and deglaciation in North America. The YDIH posits that fragments of a large, disintegrating asteroid or comet struck North America, South America, Europe, and western Asia around 12,850 years ago, coinciding with the beginning of the Younger Dryas cooling event. Multiple meteor air bursts and/or impacts are said to have produced the Younger Dryas boundary layer (YDB), depositing peak concentrations of platinum, high-temperature spherules, meltglass, and nanodiamonds, forming an isochronous datum at more than 50 sites across about 50 million km2 of Earth's surface. Some scientists have proposed that this event triggered extensive biomass burning, a brief impact winter and the Younger Dryas abrupt climate change, contributed to extinctions of late Pleistocene megafauna, and resulted in the end of the Clovis culture. A group known as the Comet Research Group are the primary advocates for the impact hypothesis, though other groups have published supporting evidence. The YDIH remains a minority and disputed view and has failed to gain acceptance by the mainstream planetary impact and paleoclimate communities.
The Lindenmeier site is a stratified multi-component archaeological site most famous for its Folsom component. The former Lindenmeier Ranch is in the Soapstone Prairie Natural Area, in northeastern Larimer County, Colorado, United States. The site contains the most extensive Folsom culture campsite yet found with a radiocarbon date of 10,600 to 10,720 B.P. Artifacts were also found from subsequent Archaic and Late pre-historic periods.
The Double Adobe site is an archaeological site in southern Arizona, twelve miles northwest of Douglas in the Whitewater Draw area. In October 1926, just three months after the first human artifact was uncovered at the Folsom site, Byron Cummings, first Head of the Archaeology Department at the University of Arizona, led four students to Whitewater Draw. Discovered by a schoolboy, the Double Adobe site contained the skull of a mammoth overlying a sand layer containing stone artifacts. One of these students was Emil Haury.
The Lehner Mammoth-Kill Site is in southern Arizona on the west bank of the San Pedro River 1.5 miles southwest of the town of Hereford. It is significant for its association with evidence that mammoths were killed here by Paleo-Indians 11, 000 to 12,000 years Before Present.
Ventana Cave is an archaeological site in southern Arizona. It is located on the Tohono O'odham Indian Reservation. The cave was excavated under the direction of Emil Haury by teams led by Julian Hayden in 1942, and in 1941 by a team led by Wilfrid C Bailey, one of Emil Haury's graduate students. The deepest artifacts from Ventana Cave were recovered from a layer of volcanic debris that also contained Pleistocene horse, Burden's pronghorn, tapir, sloth, and other extinct and modern species. A projectile point from the volcanic debris layer was compared to the Folsom Tradition and later to the Clovis culture, but the assemblage was peculiar enough to warrant a separate name – the Ventana Complex. Radiocarbon dates from the volcanic debris layer indicated an age of about 11,300 BP.
George Carr Frison was an American archaeologist. He received the Society for American Archaeology's Lifetime Achievement Award, the Paleoarchaeologist of the Century Award, and was elected to the National Academy of Sciences. He was Wyoming’s first State Archaeologist, and was a founder of the University of Wyoming Anthropology Department. He died in September 2020 at the age of 95.
Folsom site or Wild Horse Arroyo, designated by the Smithsonian trinomial 29CX1, is a major archaeological site about 8 miles (13 km) west of Folsom, New Mexico. It is the type site for the Folsom tradition, a Paleo-Indian cultural sequence dating to between 9000 BC and 8000 BC. The Folsom site was excavated in 1926 and found to have been a marsh-side kill site or camp where 32 bison had been killed using distinctive tools, known as Folsom points. This site is significant because it was the first time that artifacts indisputably made by humans were found directly associated with faunal remains from an extinct form of bison from the Late Pleistocene. The information culled from this site was the first of a set of discoveries that would allow archaeologists to revise their estimations for the time of arrival of Native Americans on the North American continent.
Blackwater Draw is an intermittent stream channel about 140 km (87 mi) long, with headwaters in Roosevelt County, New Mexico, about 18 km (11 mi) southwest of Clovis, New Mexico, and flows southeastward across the Llano Estacado toward the city of Lubbock, Texas, where it joins Yellow House Draw to form Yellow House Canyon at the head of the North Fork Double Mountain Fork Brazos River. It stretches across eastern Roosevelt County, New Mexico, and Bailey, Lamb, Hale, and Lubbock Counties of West Texas and drains an area of 1,560 sq mi (4,040 km2).
The Naco Mammoth Kill Site is an archaeological site in southeast Arizona, 1 mile northwest of Naco in Cochise County. The site was reported to the Arizona State Museum in September 1951 by Marc Navarrete, a local resident, after his father found two Clovis points in Greenbush Draw, while digging out the fossil bones of a mammoth. Emil Haury excavated the Naco mammoth site in April 1952. In only five days, Haury recovered the remains of a Columbian Mammoth in association with 8 Clovis points. The excavator believed the assemblage to date from about 10,000 Before Present. An additional point was found in the arroyo upstream. The Naco site was the first Clovis mammoth kill association to be identified. An additional, unpublished, second excavation occurred in 1953 which doubled the area of the original work and found bones from a 2nd mammoth. In 2020, small charcoal fragments were found adhered to a mammoth bone from the site. AMS radiocarbon dating produced a mean date of 10,985 ± 56 Before Present.
Caleb Vance Haynes Jr., known as Vance Haynes or C. Vance Haynes Jr., is an archaeologist, geologist and author who specializes in the archaeology of the American Southwest. Haynes "revolutionized the fields of geoarchaeology and archaeological geology." He is known for unearthing and studying artifacts of Paleo-Indians including ones from Sandia Cave in the 1960s, work which helped to establish the timeline of human migration through North America. Haynes coined the term "black mat" for a layer of 10,000-year-old swamp soil seen in many North American archaeological studies.
The Olsen–Chubbuck Bison kill site is a Paleo-Indian site that dates to an estimated 8000–6500 B.C. and provides evidence for bison hunting and using a game drive system, long before the use of the bow and arrow or horses. The site holds a bone bed of nearly 200 bison that were killed, butchered, and consumed by Paleo-Indian hunters. The site is located 16 miles southeast of Kit Carson, Colorado. The site was named after archaeologists, Sigurd Olsen and Gerald Chubbuck, who discovered the bone bed in 1957. In 1958, the excavation of the Olsen-Chubbuck site was then turned over to the University of Colorado Museum of Natural History, a team led by Joe Ben Wheat, an anthropologist employed by the museum.
Lamb Spring is a pre-Clovis prehistoric Paleo-Indian archaeological site located in Douglas County, Colorado with the largest collection of Columbian mammoth bones in the state. Lamb Spring also provides evidence of Paleo-Indian hunting in a later period by the Cody culture complex group. Lamb Spring was listed in 1997 on the National Register of Historic Places.
The Dent site is a Clovis culture site located in Weld County, Colorado, near Milliken, Colorado. It provided evidence that humans and mammoths co-existed in the Americas.
Hell Gap is a deeply stratified archaeological site located in the Great Plains of eastern Wyoming, approximately thirteen miles north of Guernsey, where an abundant amount of Paleoindian and Archaic artifacts have been found and excavated since 1959. This site has had an important impact on North American archaeology because of the large quantity and breadth of prehistoric Paleoindian and Archaic period artifacts and cultures it encompasses. It was designated a National Historic Landmark in 2016.
El Fin del Mundo is an ancient Pleistocene site near Pitiquito in northwestern Sonora, Mexico. It features Clovis culture period occupation dating around 13,390 calibrated years BP and was discovered during a 2007 survey.
