An archaeological site is a place (or group of physical sites) in which evidence of past activity is preserved (either prehistoric or historic or contemporary), 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.
Beyond this, the definition and geographical extent of a "site" can vary widely, depending on the period studied and the theoretical approach of the archaeologist.
It is almost invariably difficult to delimit a site. It is sometimes taken to indicate a settlement of some sort, although the archaeologist must also define the limits of human activity around the settlement. Any episode of deposition, such as a hoard or burial, can form a site as well. Development-led archaeology undertaken as cultural resources management has the disadvantage (or the benefit) of having its sites defined by the limits of the intended development. Even in this case, however, in describing and interpreting the site, the archaeologist will have to look outside the boundaries of the building site.
According to Jess Beck in "How Do Archaeologists Find Sites?" [1] the areas with numerous artifacts are good targets for future excavation, while areas with a small number of artifacts are thought to reflect a lack of past human activity. Many areas have been discovered by accident. The most common people who have found artifacts are farmers who are plowing their fields or just cleaning them up, and they often find archaeological artifacts. Many people who are out hiking and even pilots find artifacts, and they usually end up reporting them to archaeologists for further investigation. When they find sites, they have to first record the area, and if they have the money and time for the site, they can start digging.
There are many ways to find sites, one example can be through surveys. Surveys involve walking around analyzing the land and looking for artifacts. It can also involve digging, according to the Archaeological Institute of America, [2] "archaeologists actively search areas that were likely to support human populations, or in places where old documents and records indicate people once lived." This helps archaeologists in the future. In case there is no time or money during the site's discovery, archaeologists can come back and visit the site for further digging to find out the extent of the site. Archaeologist can also sample randomly within a given area of land as another form of conducting surveys. Surveys are very useful, according to Jess Beck, "it can tell you where people were living at different points in the past." Geophysics is a branch of survey becoming more and more popular in archaeology, because it uses different types of instruments to investigate features below the ground surface. It is not as reliable because although they can see what is under the surface of the ground, it does not produce the best picture. Archaeologists still have to dig up the area in order to uncover the truth. There are also two most common types of geophysical survey, which is, magnetometer and ground penetrating radar. Magnetometry [3] is the technique of measuring and mapping patterns of magnetism in the soil. It uses an instrument called a magnetometer, which is required to measure and map traces of soil magnetism. The ground penetrating radar [4] is a method that uses radar pulses to image the subsurface. It uses electromagnetic radiation in the microwave band of the radio spectrum and detects the reflected signals from subsurface structures.
There are many other tools that can be used to find artifacts, but along with finding artifacts, archaeologists have to make maps. They do so by taking data from surveys, or archival research and plugging it into a Geographical Information Systems (GIS) [5] and that will contain both locational information and a combination of various information. This tool is very helpful to archaeologists who want to explore in a different area and want to see if anyone else has done research. They can use this tool to see what has already been discovered. With this information available, archaeologists can expand their research and add more to what has already been found.
Traditionally, sites are distinguished by the presence of both artifacts and features. Common features include the remains of hearths and houses. Ecofacts, biological materials (such as bones, scales, and even feces) that are the result of human activity but are not deliberately modified, are also common at many archaeological sites. In the cases of the Palaeolithic and Mesolithic eras, a mere scatter of flint flakes will also constitute a site worthy of study. Different archaeologists may see an ancient town, and its nearby cemetery as being two different sites, or as being part of the same wider site. The precepts of landscape archaeology attempt to see each discrete unit of human activity in the context of the wider environment, further distorting the concept of the site as a demarcated area. Furthermore, geoarchaeologists or environmental archaeologists would also consider a sequence of natural geological or organic deposition, in the absence of human activity, to constitute a site worthy of study.
Archaeological sites usually form through human-related processes but can be subject to natural, post-depositional factors. Cultural remnants which have been buried by sediments are, in many environments, more likely to be preserved than exposed cultural remnants. Natural actions resulting in sediment being deposited include alluvial (water-related) or aeolian (wind-related) natural processes. In jungles and other areas of lush plant growth, decomposed vegetative sediment can result in layers of soil deposited over remains. Colluviation, the burial of a site by sediments moved by gravity (called hillwash) can also happen at sites on slopes. Human activities (both deliberate and incidental) also often bury sites. It is common in many cultures for newer structures to be built atop the remains of older ones. Urban archaeology has developed especially to deal with these sorts of site.
Many sites are the subject of ongoing excavation or investigation. Note the difference between archaeological sites and archaeological discoveries.
Underwater archaeology is archaeology practiced underwater. As with all other branches of archaeology, it evolved from its roots in pre-history and in the classical era to include sites from the historical and industrial eras.
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.
A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field. Other magnetometers measure the magnetic dipole moment of a magnetic material such as a ferromagnet, for example by recording the effect of this magnetic dipole on the induced current in a coil.
In archaeology, geophysical survey is ground-based physical sensing techniques used for archaeological imaging or mapping. Remote sensing and marine surveys are also used in archaeology, but are generally considered separate disciplines. Other terms, such as "geophysical prospection" and "archaeological geophysics" are generally synonymous.
Aerial archaeology is the study of archaeological sites from the air. It is a method of archaeological investigation that uses aerial photography, remote sensing, and other techniques to identify, record, and interpret archaeological features and sites. Aerial archaeology has been used to discover and map a wide range of archaeological sites, from prehistoric settlements and ancient roads to medieval castles and World War II battlefields.
Stratigraphy is a key concept to modern archaeological theory and practice. Modern excavation techniques are based on stratigraphic principles. The concept derives from the geological use of the idea that sedimentation takes place according to uniform principles. When archaeological finds are below the surface of the ground, the identification of the context of each find is vital in enabling the archaeologist to draw conclusions about the site and about the nature and date of its occupation. It is the archaeologist's role to attempt to discover what contexts exist and how they came to be created. Archaeological stratification or sequence is the dynamic superimposition of single units of stratigraphy, or contexts.
Geoarchaeology is a multi-disciplinary approach which uses the techniques and subject matter of geography, geology, geophysics and other Earth sciences to examine topics which inform archaeological and chronological knowledge and thought. Geoarchaeologists study the natural physical processes that affect archaeological sites such as geomorphology, the formation of sites through geological processes and the effects on buried sites and artifacts post-deposition.
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 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.
Archaeology or archeology is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology, history or geography.
Remote sensing techniques in archaeology are an increasingly important component of the technical and methodological tool set available in archaeological research. The use of remote sensing techniques allows archaeologists to uncover unique data that is unobtainable using traditional archaeological excavation techniques.
Magnetic surveying is one of a number of methods used in archaeological geophysics. Magnetic surveys record spatial variation in the Earth's magnetic field. In archaeology, magnetic surveys are used to detect and map archaeological artefacts and features. Magnetic surveys are used in both terrestrial and marine archaeology.
Near-surface geophysics is the use of geophysical methods to investigate small-scale features in the shallow subsurface. It is closely related to applied geophysics or exploration geophysics. Methods used include seismic refraction and reflection, gravity, magnetic, electric, and electromagnetic methods. Many of these methods were developed for oil and mineral exploration but are now used for a great variety of applications, including archaeology, environmental science, forensic science, military intelligence, geotechnical investigation, treasure hunting, and hydrogeology. In addition to the practical applications, near-surface geophysics includes the study of biogeochemical cycles.
Forensic geophysics is a branch of forensic science and is the study, the search, the localization and the mapping of buried objects or elements beneath the soil or the water, using geophysics tools for legal purposes. There are various geophysical techniques for forensic investigations in which the targets are buried and have different dimensions. Geophysical methods have the potential to aid the search and the recovery of these targets because they can non-destructively and rapidly investigate large areas where a suspect, illegal burial or, in general, a forensic target is hidden in the subsoil. When in the subsurface there is a contrast of physical properties between a target and the material in which it is buried, it is possible to individuate and define precisely the concealing place of the searched target. It is also possible to recognize evidences of human soil occupation or excavation, both recent and older. Forensic geophysics is an evolving technique that is gaining popularity and prestige in law enforcement.

Aigyr-Zhal 2 is a historical site in Naryn city on the territory of University of Central Asia (UCA), Kyrgyzstan. It is a part of a bigger and more complex site Aigyr-Zhal. It is dated between Mesolithic time and the Middle Ages. Aigyr-Zhal is the only site in the Tian-Shan that has evidence of human occupation from Mesolithic time till the Turkic period . It was first discovered in 1953 by Akhmat Kibirov. However, during the Soviet time the site was partially destroyed, therefore it was impossible to research the site for a long time. Only in 2012 it was first researched by Kubat Tabaldiev's archaeological team. The length of Aigyr-Zhal 2 is 300 metres, while the width is 100 metres, and the height of the site is 2026 metres above the sea level. Since 2002 the whole Aigyr-Zhal complex has been on the list of national importance of Kyrgyzstan.
The Lake Phelps Site is an archaeological site containing much evidence of prehistoric occupation. The lake is in North Carolina. Eleven archaeological investigations have been conducted at the lake over a course of 25 years. Altogether the investigations "recovered over 5,000 artifacts and located and documented 23 canoes." Archaeologists were able to analyze and categorize the recovered artifacts into 10 different artifact types. In addition, the archaeologists were able to provide radiocarbon dates to most of the canoes. The result of all of this provided evidence of prehistoric occupation of Lake Phelps that dated from the Late PaleoIndian/Early Archaic period through the Late Woodland period.
The Cedar Creek Earthworks Site is an earthworks site located in Essex County, Ontario. It has the Borden number of AaHq-2. This site was originally documented in Canada in the 1930s. This site has gone through several different forms of excavation throughout the years, such as remote sensing, test-pitting, and targeted test excavations. Even with these different forms of excavations and changes that have been made to the site there is still evidence of the sites cultural history.
Ian James Mathieson was a Scottish Egyptologist and Land Surveyor. He pioneered various methods of surveying and mapping of large archaeological sites avoiding the expense or intrusion of excavation.
Zilum is a settlement of the Gajiganna culture located in the Chad Basin of northeastern Nigeria, 72 km north of Maiduguri in Borno State and is dated to ca 600-400 BCE. The site itself is relatively flat, sits on a large sand ridge, and is bordered to the south by a clay depression. Zilum was discovered in 1997 by Peter Breunig and from 2000-2002, Carlos Magnavita began several test excavations at the site.
