Earthworks (archaeology)In archaeology, earthworks are artificial changes in land level, typically made from piles of artificially placed or sculpted rocks and soil. Earthworks can themselves be archaeological features, or they can show features beneath the surface. Earthworks of interest to archaeologists include hill forts, henges, mounds, platform mounds, effigy mounds, enclosures, long barrows, tumuli, ridge and furrow, mottes, round barrows, and other tombs.
MoundA mound is a heaped pile of earth, gravel, sand, rocks, or debris. Most commonly, mounds are earthen formations such as hills and mountains, particularly if they appear artificial. A mound may be any rounded area of topographically higher elevation on any surface. Artificial mounds have been created for a variety of reasons throughout history, including habitation (see Tell and Terp), ceremonial (platform mound), burial (tumulus), and commemorative purposes (e.g. Kościuszko Mound).
Woodland periodIn the classification of , the Woodland period of North American pre-Columbian cultures spanned a period from roughly 1000 BCE to European contact in the eastern part of North America, with some archaeologists distinguishing the Mississippian period, from 1000 CE to European contact as a separate period. The term "Woodland Period" was introduced in the 1930s as a generic term for prehistoric sites falling between the Archaic hunter-gatherers and the agriculturalist Mississippian cultures.
Moundville Archaeological SiteMoundville Archaeological Site, also known as the Moundville Archaeological Park, is a Mississippian culture archaeological site on the Black Warrior River in Hale County, near the modern city of Tuscaloosa, Alabama. Extensive archaeological investigation has shown that the site was the political and ceremonial center of a regionally organized Mississippian culture chiefdom polity between the 11th and 16th centuries. The archaeological park portion of the site is administered by the University of Alabama Museums and encompasses , consisting of 29 platform mounds around a rectangular plaza.
Archaic period (North America)In the classification of the , the Archaic period in North America, taken to last from around 8000 to 1000 BC in the sequence of North American pre-Columbian cultural stages, is a period defined by the archaic stage of cultural development. The Archaic stage is characterized by subsistence economies supported through the exploitation of nuts, seeds, and shellfish. As its ending is defined by the adoption of sedentary farming, this date can vary significantly across the Americas. The rest of the Americas also have an Archaic Period.
Mississippian cultureThe Mississippian culture was a Native American civilization that flourished in what is now the Midwestern, Eastern, and Southeastern United States from approximately 800 CE to 1600 CE, varying regionally. It was known for building large, earthen platform mounds, and often other shaped mounds as well. It was composed of a series of urban settlements and satellite villages linked together by loose trading networks. The largest city was Cahokia, believed to be a major religious center located in what is present-day southern Illinois.
MesoamericaMesoamerica is a historical region and cultural area that begins in the southern part of North America and extends to most of Central America, thus comprising the lands of central Mexico, Belize, and Guatemala, El Salvador, Honduras, and Nicaragua, and northern Costa Rica. In the pre-Columbian era, many societies flourished in Mesoamerica for more than 3,000 years before the Spanish colonization of the Americas begun at Hispaniola island in 1493.
Hopewell traditionThe Hopewell tradition, also called the Hopewell culture and Hopewellian exchange, describes a network of precontact Native American cultures that flourished in settlements along rivers in the northeastern and midwestern Eastern Woodlands from 100 BCE to 500 CE, in the Middle Woodland period. The Hopewell tradition was not a single culture or society but a widely dispersed set of populations connected by a common network of trade routes.
CahokiaThe Cahokia Mounds State Historic Site kəˈhoʊkiə (11 MS 2) is the site of a pre-Columbian Native American city (which existed 1050–1350 CE) directly across the Mississippi River from present-day St. Louis, Missouri. This historic park lies in south-western Illinois between East St. Louis and Collinsville. The park covers , or about , and contains about 80 manmade mounds, but the ancient city was much larger. At its apex around 1100 CE, the city covered about and included about 120 earthworks in a wide range of sizes, shapes, and functions.
Mound BuildersA number of pre-Columbian cultures in North America were collectively termed "Mound Builders", but the term has no formal meaning. It does not refer to a specific people or archaeological culture, but refers to the characteristic mound earthworks which indigenous peoples erected for an extended period of more than 5,000 years. The "Mound Builder" cultures span the period of roughly 3500 BCE (the construction of Watson Brake) to the 16th century CE, including the Archaic period, Woodland period (Calusa culture, Adena and Hopewell cultures), and Mississippian period.
