Archaeological sites

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?” the areas with a large number of artifacts are good targets for future excavation, while areas with small number of artifacts are thought to reflect a lack of past human activity.” Many areas have been discovered by accident. The most common person to have found artifacts are farmers who are plowing their fields or just cleaning them up often find archaeological artifacts. Many people who are out hiking and even pilots find artifacts they usually end up reporting them to archaeologist to do 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 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.” 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 have to still 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 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 is a method that uses radar pulses to image the subsurface. It uses electro magnetic radiation in the microwave band of the radio spectrum, and detects the reflected signals from subsurface structures.
