How do archaeologists know when to stop digging?

Archaeologists learn how to identify changes that they see in sediments in archaeological sites. Archaeologists have stopped digging at sites once they encounter Clovis cultural remains at sites. They have assumed the sediments below to be ‘sterile’ and stop digging.

Why do archaeologists have to be careful when digging?

Excavation is a detailed and careful process, and knowing how it is completed at a site can have implications for the research and interpretations. First there is the interpretation of the burial itself- it is important to excavate carefully to make sure all evidence is collected.

How long does an archaeological dig last?

Digging is slow, and most sites are big – so a dig can take many seasons. A single season can be anywhere from one week to a couple of months; it’s rare for an excavation season to last longer than that.

Do archaeologists spend all of their time digging?

But in reality… Archaeology is more than digging. Archaeologists do not spend a lot of time excavating. Instead, they spend a lot of time in the laboratory, analyzing and interpreting their finds.

How do archaeologists know where to dig?

To determine where a site might be, archaeologists conduct a survey, which can include walking through a site and digging holes of similar depths at an equal distance apart from each other, known as shovel test pits, as well as GPS, resistivity meters, and ground penetrating radars.

How deep do archaeologists dig?

The number of levels we dig for each excavation unit varies depending on the site. Sometimes a finished unit will be fairly shallow, maybe 30cm down. Sometimes it will be deep, up to 1 meter in depth. Archaeologists use many types of tools to excavate.

Why does it take archaeologist many years to excavate a site?

How long it takes to excavate an archaeological dig site all depends on how much cash a dig team has to get the job done. In fact, to even begin most archaeological excavations, funding has to be in place. And the amount of money the project has in place typically determines the length of the dig, in most cases.

What do archaeologists do on a dig?

Archaeologists dig up and study the physical (material) remains of people who lived long ago, including their public architecture, private houses, art, objects of daily life, trash, food, and more, to answer questions about who the people were, how they lived, what they ate, and what their lives were like.

What do archaeologists call digging?

excavation
In archaeology, excavation is the exposure, processing and recording of archaeological remains. An excavation site or “dig” is the area being studied.

How do archaeologists find ancient sites without digging?

There are non-invasive techniques archaeologists can use to find sites without digging. Examples of geophysical surveys that do not disturb the soil include magnetometry, resistivity, and ground-penetrating radar.

How has archaeological investigation changed over the years?

P ractices in archaeological investigation have also changed dramatically. During the 1800s, most archaeologists treated human remains as valuable artifacts and spared little concern for the ethics of digging them up.

What does an archaeologist do when conducting an archaeological survey?

First they will check if there were any previous surveys in the area and, if so, what the results were. If there are no previously recorded sites, the archaeologist will conduct an archaeological survey. If there are sites, the archaeologist will want to know how many, their locations, and how the sites relate to each other.

How do archaeologists record the location of artifacts?

Archaeologists must record the exact location of all artifacts and features on a site. Before removing any soil or artifacts from a site, they create a site grid. They establish a datum point, or fixed reference point for all measurements. Then they superimpose a rectangular grid over the whole site.
