Recent intensive study of the sequence of deposits in a small area of the cave, using primarily sedimentological and palaeontological techniques, has revealed the presence of three main units, dating from the Late Devensian, from a full glacial episode (probably Devensian) and from an interglacial episode (possibly but by no means certainly Ipswichian). Re-examination of the finds and literature associated with the old excavations generally supports these conclusions. New radiocarbon dates suggest that the brief Palaeolithic intrusion, evidenced by flint artefacts and human bones from the old collections, occurred very near the end of the Devensian Glacial. Multidisciplinary work continues at this site.
