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. archaeological sites ancient ruins guide
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.
There are many ways to find sites, one example can be through surveys. Surveys involve walking around analyzing the land looking for artifacts. It can also involve digging, according to the Archaeological Institute of America,“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 was no time, or money during the finding of the site, 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.
