Stratigraphy

Stratigraphy gives archaeologists evidence about people who lived in the past. Researchers document location, layers, materials, damage, associated objects, and environmental context before drawing conclusions. An artifact by itself can be interesting, but its exact location and relationship to other finds often provide the most useful information. Archaeology also depends on conservation, ethics, local laws, collaboration with descendant communities, and careful scientific recording.
