The archaeologists have finished working in thei
r first area of exploration. Before moving to another area, they worked to clean, photograph, and create measured drawings of the profile (vertical walls) of the trench. Like a birthday cake, the ground beneath our feet has layers. Archaeologists use these layers to group artifacts and date them by their association to one-another (Relative Dating).

In addition, the photographs and scale drawings help archaeologists keep careful track of their findings. Archaeology is a destructive science; once an area is excavated, it can never be excavated again. Therefore, careful documentation is very important.
