Cropmark
|
Cropmarks appear as light and dark marks in growing and ripening crops. These marks relate to differences in the soil below. For example, parched lines of grass may indicate stone walls. Crops that grow over stone features often ripen more quickly and are shorter than the surrounding crop. This is because there is less moisture in the soil where the wall lies.

excavation
|
Archaeologists excavate sites so that they can find information and recover archaeological materials before they are destroyed by erosion, construction or changes in land-use.
Depending on how complicated and widespread the archaeological deposits are, excavation can be done by hand or with heavy machinery. Archaeologists may excavate a site in a number of ways; either by open area excavation, by digging a test pit or a trial trench.

Aerial Photograph
|
Aerial photographs are taken during an aerial survey, which involves looking at the ground from above. It is usually easier to see cropmarks and earthworks when they are viewed from above. Aerial photographs help archaeologists to record what they see and to identify new sites. There are two kinds of aerial photographs; oblique and vertical.
