How archaeology works: How archaeologists find, dig, and interpret a site

By the end of this unit, you'll be able to explain what archaeology actually studies, how archaeologists choose where to dig, and what happens to an artifact once it's out of the ground. You'll trade the Indiana Jones version of archaeology for the real, patient process behind it.

Archaeology reconstructs how people lived from what they left behind: a broken pot, a house foundation, a scatter of old seeds. Before any of that makes sense, you need to know what actually counts as evidence, and why the same object can mean two completely different things depending on where it turns up.

Age alone doesn't make an object archaeological evidence. Context makes it useful: where it was found, what sat next to it, and which soil layer it came from. Strip that away, and the object becomes a curiosity instead of a clue about how someone actually lived. What even is archaeology? draws the line between an archaeologist, a historian, and a paleontologist, and explains why a rusted nail can matter as much as a gold coin.

Most people picture archaeology starting with a shovel. Still, the real first step is deciding where to dig at all, sometimes from old maps and satellite images, sometimes from a farmer mentioning something odd turned up in a field. A promising spot is still just a guess until someone tests it. Finding a site covers how that search really works, and why most likely spots never get excavated.

Once a site is chosen, digging goes deliberately slow. Every layer of soil gets mapped and recorded before it's removed, because that information disappears the moment the soil does. Digging with a plan explains why archaeologists work in small marked squares instead of trenching straight through a site, and what that carefulness is protecting.

This is currently the only unit under Archaeology, so there's no earlier unit to finish first and nothing else it assumes you already know. It simply follows the order the work happens: what archaeology studies, how a site gets found, how it gets excavated, and then what happens to whatever comes out of the ground. That last part, the life of a find after the dig ends, is usually the part people know least about.

This unit covers the mechanics: what archaeology studies and how a dig runs from start to finish. Other parts of archaeology, like specific civilizations or well-known discoveries, build on that foundation rather than replacing it. Once you know how a dig actually works, a headline about a newly found site reads very differently. For the wider map of what archaeology as a subject covers, How to learn archaeology? is where to start.
