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 13,400–12,700 years ago. As an example, Clovis remains at the Murry Springs Site date to around 12,900 calendar 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 an archaeological culture from the Paleoindian period of North America, spanning around 13,050 to 12,750 years Before Present (BP). The type site is Blackwater Draw locality No. 1 near Clovis, New Mexico, where stone tools were found alongside the remains of Columbian mammoths in 1929. Clovis sites have been found across North America. The most distinctive part of the Clovis culture toolkit are Clovis points, which are projectile points with a fluted, lanceolate shape. Clovis points are typically large, sometimes exceeding 10 centimetres (3.9 in) in length. These points were multifunctional, also serving as cutting tools. Other stone tools used by the Clovis culture include knives, scrapers, and bifacial tools, with bone tools including beveled rods and shaft wrenches, with possible ivory points also being identified. Hides, wood, and natural fibers may also have been utilized, though no direct evidence of this has been preserved. Clovis artifacts are often found grouped together in caches where they had been stored for later retrieval, and over 20 Clovis caches have been identified.
Monte Verde is a Paleolithic archaeological site in the Llanquihue Province in southern Chile, located near Puerto Montt, Los Lagos Region. The site is primarily known for Monte Verde II, dating to approximately 14,550–14,500 calibrated years Before Present (BP). The Monte Verde II site has been considered key evidence showing that the human settlement of the Americas pre-dates the Clovis culture by at least 1,000 years. This contradicts the previously accepted "Clovis first" model which holds that settlement of the Americas began after 13,500 cal BP. The Monte Verde findings were initially dismissed by most of the scientific community, but the evidence then became more accepted in archaeological circles. The site also contains an older, much more controversial layer suggested to date to 18,500 cal BP, that lacks the general acceptance of Monte Verde II.
The Meadowcroft Rockshelter is an archaeological site which is located near Avella in Jefferson Township, Pennsylvania. The site is a rock shelter in a bluff overlooking Cross Creek, and contains evidence that the area may have been continually inhabited for more than 19,000 years. If accurately dated, it would be one of the earliest known sites with evidence of a human presence and continuous human occupation in the New World.
The Big Eddy Site (23CE426) is an archaeological site located in Cedar County, Missouri, which was first excavated in 1997 and is now threatened due to erosion by the Sac River.
Emil Walter "Doc" Haury was an American archaeologist who specialized in the archaeology of the American Southwest. He is most famous for his work at Snaketown, a Hohokam site in Arizona.
James M. Adovasio is an American archaeologist and one of the foremost experts in perishable artifacts. He was formerly the Provost, Dean of the Zurn School of Natural Sciences and Mathematics, and Director of the Mercyhurst Archaeological Institute at Mercyhurst University in Erie, Pennsylvania, Adovasio is best known for his work at Meadowcroft Rockshelter in Pennsylvania and for his subsequent role in the "Clovis First" debate. He has published nearly 400 books, monographs, articles, and papers in his field.
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.
The Paisley Caves or the Paisley Five Mile Point Caves complex is a system of eight caves in an arid, desolate region of south-central Oregon, United States north of the present-day city of Paisley, Oregon. The caves are located in the Summer Lake basin at 4,520 feet (1,380 m) elevation and face west, carved into a ridge of Miocene and Pliocene era basalts mixed with soft volcanic tuffs and breccias by Pleistocene-era waves from Summer Lake. One of the caves may contain archaeological evidence of the oldest definitively-dated human presence in North America. The site was first studied by Luther Cressman in the 1930s.
Mumba Cave, located near the highly alkaline Lake Eyasi in Karatu District, Arusha Region, Tanzania. The cave is a rich archaeological site noted for deposits spanning the transition between the Middle Stone Age and Late Stone Age in Eastern Africa. The transitional nature of the site has been attributed to the large presence of its large assemblage of ostrich eggshell beads and more importantly, the abundance of microlith technology. Because these type artifacts were found within the site it has led archaeologists to believe that the site could provide insight into the origins of modern human behavior. The cave was originally tested by Ludwig Kohl-Larsen and his wife Margit in their 1934 to 1936 expedition. They found abundant artifacts, rock art, and burials. However, only brief descriptions of these findings were ever published. That being said, work of the Kohl-Larsens has been seen as very accomplished due to their attention to detail, especially when one considers that neither was versed in proper archaeological techniques at the time of excavation. The site has since been reexamined in an effort to reanalyze and complement the work that has already been done, but the ramifications of improper excavations of the past are still being felt today, specifically in the unreliable collection of C-14 data and confusing stratigraphy.
Enkapune Ya Muto, also known as Twilight Cave, is a site spanning the late Middle Stone Age to the Late Stone Age on the Mau Escarpment of Kenya. This time span has allowed for further study of the transition from the Middle Stone Age to the Late Stone Age. In particular, the changes in lithic and pottery industries can be tracked over these time periods as well as transitions from a hunter-gatherer lifestyle to a herding lifestyle. Beads made of perforated ostrich egg shells found at the site have been dated to 40,000 years ago. The beads found at the site represent the early human use of personal ornaments. Inferences pertaining to climate and environment changes during the pre-Holocene and Holocene period have been made based from faunal remains based in this site.
The Windust Caves (45-FR-46) are a series of nine caves eroded into a basalt cliff on the north side of the lower Snake River in Franklin County, southeastern Washington. The caves were excavated from 1959 until 1961 by a crew led by Harvey S. Rice. The site contains cultural artifacts dating back over 10,000 years and is culturally associated with other sites in the Columbia Basin.
Cueva Fell or Fell'sCave is a natural cave and archaeological site in southern Patagonia. Cueva Fell is in proximity to the Pali Aike Crater, another significant archaeological site. Cueva Fell combined with the nearby Pali Aike site have been submitted to UNESCO as a possible World Heritage Site.
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 in Arizona. 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 Buttermilk Creek complex is the remains of a paleolithic settlement along the shores of Buttermilk Creek in present-day Salado, Texas. The assemblage dates to ~13.2 to 15.5 thousand years old. If confirmed, the site represents evidence of human settlement in the Americas that pre-dates the Clovis culture.
Vance T. Holliday is a professor in the School of Anthropology and the department of Geosciences as well as an adjunct professor in the department of Geography at the University of Arizona in Tucson.
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.
The theory known as "Clovis First" was the predominant hypothesis among archaeologists in the second half of the 20th century to explain the peopling of the Americas. According to Clovis First, the people associated with the Clovis culture were the first inhabitants of the Americas. This hypothesis came to be challenged by ongoing studies that suggest pre-Clovis human occupation of the Americas. In 2011, following the excavation of an occupation site at Buttermilk Creek, Texas, a group of scientists identified the existence "of an occupation older than Clovis." At the site in Buttermilk, archaeologists discovered evidence of hunter-gatherer group living and the making of projectile spear points, blades, choppers, and other stone tools. The tools found were made from a local chert and could be dated back to as early as 15,000 years ago.
