Fieldwalking is used to map where archaeological objects are found across the surface of ploughed fields.
There are two main types: line walking and grid walking.
Line walking is where a group of fieldwalkers walk alongside each other spread across the site. They walk forwards in a straight line, collecting finds (such as worked flint or pottery) as they go. Each ‘line’ is split into sections usually called ‘stints’; finds are bagged up depending on which line and stint they were found within.
In grid walking, the survey area is split into squares. Each fieldwalker is given a square to search for finds in a set length of time. Finds are then bagged up by grid square. Both these methods allow archaeologists to map where there are find ‘hotspots’ across a site. The pattern of finds might then help them to decide where to place their trenches in an excavation.
