Discussion

This is one of at least 15 quarry pits Click for a plan of all the quarry pits in the area on the western edge of the dry valley,  all of which appear to be later Roman in date, cut to extract the white chalk found in this vicinity. The pit contained three fills, although the second fill was not initially noted as the pit was very rapidly excavated. The primary fill (012AD05313) was a redeposited chalk natural (50% chalk) in a sandy silty loam matrix (Munsell colour 10YR 4/3). There was no daub or charcoal flecking, and no finds were recovered from this fill. It was sealed by a fill seen only in sectio, which had a much lower density of chalk inclusions (20%, generally smaller). The final fill was 012AD05311. a sandy silty loam (Munsell colour 10YR 4/3) with 15% chalk inclusions, some quite large and angular. This upper fill contained all of the finds recovered from the quarry pit.

The pit was cut into natural chalk, with a U-shaped profile.
