Archaeology Archaeologists mapping their finds at Pachacamac, Peru, an Indigenous town occupied from approximately 200 bce to 1532 ce, when it was sacked by conquistadors under the command of Francisco Pizarro.

In archaeology, excavation is often described as a form of destruction because it involves the physical removal and alteration of the buried landscape to recover material remains. By its very nature, the process of digging—even when performed with the utmost professional care—permanently disturbs the original context and integrity of a site.12

Because this process is inherently destructive, the archaeologist’s field notes, diagrams, surveys, and published reports serve as the primary archaeological documents. These records are essential because they represent the only way to preserve the information gathered during the dig; they allow subsequent researchers to re-create and reinterpret the findings after the original site has been altered or, in cases of total excavation, completely removed.12

Ultimately, the discipline relies on the ethical principle that because a site can only be excavated once, the quality of the documentation is the only safeguard against the permanent loss of historical knowledge.12
