The trench section between the possible Dovecote (on the right) and an exterior wall of a building (on the left). Archaeologists take a lot of care about their sections, trying to ensure that they are straight and clean, as they offer a great opportunity to see a vertical slice through a feature or site (if a baulk or trench edge). When cleaned and photographed (archival photographs are always taken with a scale, unlike here) the section is then drawn to scale (measured off a horizontal line) with different deposits and features illustrated. The location of the section will be added to a scale plan, and levels taken, so it is fully located allowing people to in years to come understand exactly where it was located, and if required, reinterpret the archaeology.
