What difference does it make if the artifacts get moved?

Archeological context refers to the arrangement or position of archeological data within the soil matrix, and associations with other artifacts and ecofacts. Archeological context provides important clues regarding past human behaviors. When a park visitor removes an artifact from a site, that artifact loses its value because it has been removed from its context. Context, also called provenience, is the most important aspect of an artifact. It allows the archeologist to study the artifact in relation to its stratigraphy, natural environment, cultural environment, and surrounding artifacts.
Every object exists in many relative dimensions at once. Around it is a rich network of associations and contrasts that can be followed through to interpret its meaning. An artifact's social context encompasses interpretations of its technical production and use, its values to the people who made and used it, and perhaps how and if the object symbolized their ideology. If an artifact's archeological context is lost, its social context is also lost unless otherwise recorded.

See the importance of provenience when archeologists recovered evidence for the movement of individual firearms over the battlefield, verified cavalry positions, and defined previously unknown Indian fighting areas.
