added by archaeologs In excavation, the exposing of a deposit vertically to reveal the stratigraphy of a site or details of a particular feature. A balk is left across a feature or a complex of features, or a hole is cut out of a feature and trimmed to a flat face in which layers and changes in soil color may be examined. Sections automatically occur when the grid method of excavation is used, on all four sides of each trench. The term is also applied to the drawing of the vertical record of the stratification of a site or feature. A section drawing is a two-dimensional rendering, at a constant scale, depicting archaeological data and matrix as seen in the wall of an excavation. Advocates of open-area excavation prefer not to have standing sections on the site; instead of drawing sections after the whole area has been excavated, they record the profile of each deposit as it is excavated and construct what are known as 'cumulative' or 'running sections'.
