Excavation of archaeological sites is a destructive process, and therefore it must be a scientific process. Professional archaeologists painstakingly measure and record every square inch (or cm) of the site that they are destroying. They record this data using transits, tape measures, line levels, mapping squares, and grid sheets to name a few of the tools employed. Profiles of soil changes are produced; photographs of the excavation record the process and preserve what the eye is seeing. Archaeologists know that once they dig beneath the ground surface, that they have forever removed a portion of history contained in that landscape and that the preservation of maps and images are essential records. The history of that plot of ground is dependent on how well archaeologists document what they observe in those soils, and the careful recovery of the physical evidence of past inhabitants. Artifacts are the evidence left by those before us and serve as the physical connection to our past.

Curation of the documentation associated with archaeological investigations and the preservation of artifacts assists archaeologists in documenting and interpreting past human behavior. Researchers scour the documentation for information that facilitates our understanding of prehistory from how stone tools were produced and used, to the house sturctures of our early Native American population.
This excavation of a house structure provides the archaeological evidence of this type of structure and improves our understanding of Native American prehistory.

The historic record is often enhanced or corrected by our archaeological evidence recovered from our more recent past. History documents significant events or people, but archaeology provides a picture into the everyday life of peoples who are often left out of the historic record. Our past is our cultural heritage and the preservation of this heritage is facilitated through curation. Most of us have a connection to something from our past which we treasure, it may be an object, a letter, a photograph or a memory but it is that piece in our lives that provides us with a link to our individual past. Think of how you would feel if this was then taken from you and that connection to your past was gone. Hopefully this blog has provided our followers with a better understanding of the important role curation plays in the preservation of our heritage.
