In archaeology, excavation is the exposure, processing and recording of archaeological remains. An excavation site or "dig" is the area being studied. These locations range from one to several areas at a time during a project and can be conducted over a few weeks to several years.
An archaeological site is a place in which evidence of past activity is preserved, and which has been, or may be, investigated using the discipline of archaeology and represents a part of the archaeological record. Sites may range from those with few or no remains visible above ground, to buildings and other structures still in use.
MOLA is an archaeology and built heritage practice and independent charitable company registered with the Chartered Institute for Archaeologists (CIfA), providing a wide range of professional archaeological services to clients in London and across the country. It is one of the largest archaeological service providers in the UK, and is the only one with IRO status.
Rescue archaeology, sometimes called commercial archaeology, preventive archaeology, salvage archaeology, contract archaeology, developer-funded archaeology or compliance archaeology, is state-sanctioned, archaeological survey and excavation carried out in advance of construction or other land development. Other causes for salvage digs can be looting and illegal construction. One effect of rescue archaeology is that it diverts resources and impacts pre-planned archaeological work.
In archaeological excavation, a feature is a collection of one or more contexts representing some human non-portable activity, such as a hearth or wall. Features serve as an indication that the area in which they are found has been interfered with in the past, usually by humans.
Planning Policy Guidance 16: Archaeology and Planning commonly abbreviated as PPG 16, was a document produced by the UK Government to advise local planning authorities in England and Wales on the treatment of archaeology within the planning process. It was introduced in November 1990 following public outcry after a number of high-profile scandals such as the threatened destruction of the Rose Theatre in London by developers. It replaced the earlier Circular 8/87 which was criticized for being ill-focused in both practical and geographical terms. On 23 March 2010 the Government published 'Planning Policy Statement 5:Planning and the Historic Environment' replacing and cancelling PPG16 and PPG15 which had dealt with the rest of the historic environment.
Trial trenching is a rapid and relatively inexpensive method of archaeological evaluation used to estimate the archaeological potential of a site.
Aerial archaeology is the study of archaeological remains by examining them from a higher altitude. In present day, this is usually achieved by satellite images or through the use of drones.
Urban archaeology is a sub discipline of archaeology specializing in the material past of towns and cities where long-term human habitation has often left a rich record of the past. In modern times, when someone talks about living in a city, they are in an area with many surrounding people and buildings, generally quite tall ones. In archaeological terms, cities give great information because of the infrastructure they have and amounts of people that were around one another. Through the years there has been one big method used for Urban archaeology along with significant historic developments.
In the field of archaeology a deposit model is a method of identifying the character and degree of survival of buried archaeological remains over a specified area without necessarily excavating the whole area.
Prehistoric archaeology is a subfield of archaeology, which deals specifically with artefacts, civilisations and other materials from societies that existed before any form of writing system or historical record. Often the field focuses on ages such as the Stone Age, Bronze Age and Iron Age, although it also encompasses periods such as the Neolithic. The study of prehistoric archaeology reflects the cultural concerns of modern society by showing interpretations of time between economic growth and political stability. It is related to other disciplines such as geology, biology, anthropology, historiography and palaeontology, although there are noticeable differences between the subjects they all broadly study to understand; the past, either organic or inorganic or the lives of humans. Prehistoric archaeology is also sometimes termed as anthropological archaeology because of its indirect traces with complex patterns.
The Chartered Institute for Archaeologists (CIfA) is a professional organisation for archaeologists working in the United Kingdom and overseas. It was founded in 1982, and at 21 July 2020 had 3,931 members overall, of whom 3,033 were accredited professionals; it also has 80 accredited organisations.
In archaeology, survey or field survey is a type of field research by which archaeologists search for archaeological sites and collect information about the location, distribution and organization of past human cultures across a large area. Archaeologists conduct surveys to search for particular archaeological sites or kinds of sites, to detect patterns in the distribution of material culture over regions, to make generalizations or test hypotheses about past cultures, and to assess the risks that development projects will have adverse impacts on archaeological heritage. The surveys may be: (a) intrusive or non-intrusive, depending on the needs of the survey team and; (b) extensive or intensive, depending on the types of research questions being asked of the landscape in question. Surveys can be a practical way to decide whether or not to carry out an excavation, but may also be ends in themselves, as they produce important information about past human activities in a regional context.
Cultural heritage management (CHM) is the vocation and practice of managing cultural heritage. It is a branch of cultural resources management (CRM), although it also draws on the practices of cultural conservation, restoration, museology, archaeology, history and architecture. While the term cultural heritage is generally used in Europe, in the USA the term cultural resources is in more general use specifically referring to cultural heritage resources.
The archaeological record is the body of physical evidence about the past. It is one of the core concepts in archaeology, the academic discipline concerned with documenting and interpreting the archaeological record. Archaeological theory is used to interpret the archaeological record for a better understanding of human cultures. The archaeological record can consist of the earliest ancient findings as well as contemporary artifacts. Human activity has had a large impact on the archaeological record. Destructive human processes, such as agriculture and land development, may damage or destroy potential archaeological sites. Other threats to the archaeological record include natural phenomena and scavenging. Archaeology can be a destructive science for the finite resources of the archaeological record are lost to excavation. Therefore, archaeologists limit the amount of excavation that they do at each site and keep meticulous records of what is found. The archaeological record is the physical record of human prehistory and history, of why ancient civilizations prospered or failed and why those cultures changed and grew. It is the story of the human world.
Gatecliff Rockshelter (26NY301) is a major archaeological site in the Great Basin area of the western United States that provides remarkable stratigraphy; it has been called the "deepest archaeological rock shelter in the Americas". Located in Mill Canyon of the Toquima Range in the Monitor Valley of central Nevada, Gatecliff Rockshelter has an elevation of 7,750 feet (2,360 m). David Hurst Thomas discovered Gatecliff Rockshelter in 1970 and began excavations in 1971. Full scale excavations occurred at Gatecliff Rockshelter for about seven field seasons in which nearly 33 feet (10 m) of sediments were exposed for a well-defined stratigraphic sequence. The well-preserved artifacts and undisturbed sediments at Gatecliff Rockshelter provides data and information have been applied to a range of research topics. Based on the analysis of the artifacts at Gatecliff Rockshelter, it can be determined that it was most likely a short-term field camp throughout prehistory. The latest evidence for human usage at Gatecliff occurs between ca. 5500 B.P. to 1250 B.P.
The Shengavit Settlement is an archaeological site in present-day Yerevan, Armenia located on a hill south-east of Yerevan Lake. It was inhabited during a series of settlement phases from approximately 3000 BC cal to 2500 BC cal in the Kura Araxes (Shengavitian) Period of the Early Bronze Age and irregularly re-used in the Middle Bronze Age until 2200 BC cal. The town occupied an area of six hectares. It appears that Shengavit was a societal center for the areas surrounding the town due to its unusual size, evidence of surplus production of grains, and metallurgy, as well as its monumental 4 meter wide stone wall. Three smaller village sites of Moukhannat Tepe, Khorumbulagh, and Tairov have been identified and were located outside the walls of Shengavit. Its pottery makes it a type site of the Kura-Araxes or Early Transcaucasian Period and the Shengavitian culture area.
The Cherry Creek Rockshelter is an archaeological site in central Colorado, located within modern-day Castlewood Canyon State Park near Franktown, Colorado. Current research indicates that it was used by Native American inhabitants beginning in the Archaic period. The site is situated on the Palmer Divide, which allowed for a unique prehistoric environment that contributed to an abundance of food and water sources, as well as lithic materials for tool-making. These factors, combined with the structure and situation of the shelter itself, made the site a particularly attractive environment for prehistoric peoples to settle in. Archaeological study of the site began in 1955, with the most current original research concluding in 2002.
The conservation and restoration of archaeological sites is the collaborative effort between archaeologists, conservators, and visitors to preserve an archaeological site, and if deemed appropriate, to restore it to its previous state. Considerations about aesthetic, historic, scientific, religious, symbolic, educational, economic, and ecological values all need to be assessed prior to deciding the methods of conservation or needs for restoration. The process of archaeology is essentially destructive, as excavation permanently changes the nature and context of the site and the associated information. Therefore, archaeologists and conservators have an ethical responsibility to care for and conserve the sites they put at risk.
