excavation, or "digs", are the most important means by which archeologists get their information. by examining aerial photographs, old pictures, maps, documents or landmarks,they make the decision about where a good place might be to dig. after painstakingly removing layer of soil , often using small tools and trowels, they look for artifacts. this process continues until they reach an undisturbed layer of soil which has no trace of human occupation.
brushing away the soil that hides artifacts is like brushing away the time. the tiny fragments help to create a more complete picture of the past. although archaeology is the study of the remains of past human societies, it is not the same as history. historians use written records to find out about the past, whereas archaeologists use the objects they find such as pots, bones, and tools to find out about the past.
