|Sue completing her plan view on a framed grid|
To do this you take a plumb bob and rulers (or a framed grid) and you make a map of your unit that includes everything you, the archaeologist, sees. Why do this if we can just take a picture? The reason for mapping out your unit is because a picture is really just a reference. A camera cannot see some of the differences in soil color or disturbances. By mapping out the unit by hand you can include those details that a photo leaves out. Also, by mapping out the units there is a reference to look at when looking back at a dig site. Another aspect of archaeology I learned today was making a profile view graph. This graph maps out the depth of certain layers of soil that you may be working in. In my profile view I was mapping only layer A, but in my graph I noted when the soil changed color and drew that line in my graph. This is an important part of the process because it gives you a synopsis of what was happening in the unit as it was dug into and gives us a view of how the site was formed over time.
