Cropmarks show as differential growth in arable crops caused by the presence of sub-surface archaeological features. They are most easily visible from the air, and aerial photography has recorded many thousands. Sometimes they are so clear that they can be seen from the ground or from high buildings or hillsides.
Soil in a buried ditch or pit is still likely to hold some moisture even though it is now beneath a layer of uniform ploughsoil. When crops such as barley or wheat grow, their roots find this moisture. Those stalks that are rooted in this moisture-holding soil grow slightly quicker and taller than the rest of the crop. Sunlight, particularly early or late in the day when the sun is low in the sky, can cast a very clear shadow over the different crop heights, revealing the shape and size of the buried archaeological features. Sometimes cropmarks extend over many square miles and whole multi-period landscapes of super-imposed features ('palimpsests') are visible.
