An excavation site is a location where archaeologists and other researchers DIG to uncover artifacts and other evidence of past civilizations. The term 'excavation site' can refer to a DIG, a SANDPIT, or a RUIN. A DIG is an area where archaeologists use tools to uncover artifacts and other evidence. A SANDPIT is an area where sand is removed to reveal artifacts and other evidence. A RUIN is an area where the remains of a structure are visible. All three of these terms are used to describe an excavation site.
