Cereals growing over archaeological features ripen at different rates. Where there are buried pits and gullies the crops darken and ripen earlier as there is greater moisture content in the ground. Where crops grow over buried walls they become deprived of nutrients and the crops are thinner and lighter in colour. These patterns are particularly apparent from the air.
