It's not easy finding the remains of an ancient culture. As years pass,
buildings and artifacts get buried under dirt, rubble, or even other settlements. Archaeologists have to dig underground to find these remains.
But finding the right place, or "site," to dig is the first challenge.
Archaeologists don't just dig anywhere. They look for a site they think will help answer their questions about the people or time they are studying.
This takes a lot of planning and research. Before digging begins, archaeologists survey the site, and then create a map of it to help them decide where to dig.
