Anticipating a major extension to the site that had been previously investigated by Cambridgeshire Archaeology in 1991/92, an assessment was undertaken in the fields both north and south of the quarry. An extremely high density of surface lithics was recovered throughout, their character suggesting that the large flint cobbles within the terraces gravels were utilized for production. A later Neolithic site was recognized as a distinct surface spread in the north field, no features were however found to survive in association. Two cremations were recovered during the course of trial trenching across a ring ditch within the southern field. Evidently a ploughed-out barrow, during the later Bronze Age the monument apparently became a focus for flintworking: great quantities of ‘industrial’-type debris were recovered across its interior and in its re-cut ditch. Across the terrace is a dense cropmark network of field systems and associated settlement compounds, all evidently of Romano-British date. A droveway and parallel field boundary (the latter interrupting over the above described barrow) were sample excavated within the southern field; in the northern; a series of conjoining settlement enclosures. There is important evidence of Roman-to-(Post-) Medieval continuity inasmuch as a flanking ditch of an early droveway dictates the hedge-line bordering the present approach track to the quarry. In the north field a fine Middle Saxon brooch was recovered during fieldwalking. Subsequent metal detection survey indicated that it could not be cemetery associated. Th findspot was trial trenched and the brooch found to derive from the artifact backfill of a Grubenhaus. Whilst apart from a fenceline our investigation revealed no other contemporary features, the location of at least one other such house is suggested by a surface find of Saxon pottery.
