A student helps map elevations with surveying equipment. Knowing how deep they are digging is critical to archaeologists’ work, so preparations require taking initial elevations of the ground. As they dig, the crew will measure everything in centimeters.
Another part of preparations is marking bags for artifacts. All the dirt is screened and any artifacts put into the bag that corresponds to the layer of earth it was taken from. This helps archaeologists know what objects were found near the surface and what was deeper.
