Final answer:
The drawing of a grid at an archaeological site is a systematic method used for organizing and precisely documenting the location of artifacts during an excavation, maintaining their archaeological context.
Step-by-step explanation:
The drawing of a grid at an archaeological site refers to a method used by archaeologists to organize and document the spatial location of artifacts and features discovered during an excavation. This process involves creating a Hippodamian plan, a type of systematic grid layout, which divides the site into measured square sections to enable precise mapping. Artifacts and features within each grid square are meticulously recorded with catalog or accession numbers for proper documentation in situ. This methodical process is integral for maintaining the archaeological context of the findings, which is crucial for understanding their historical significance and associations.
