References to palaeolithic implements from the Pleistocene deposits in the Buckinghamshire parish of Iver have appeared from time to time in the Proceedings of learned societies. The British Museum Guide to Antiquities of the Stone Age, 1926, p. 46, mentions artifacts from this district, where palaeoliths have been collected for nearly half a century, but a general summary has not been made showing the sequence of cultures and the significance of the relics from the local deposits. The author has had the commercial workings in the Iver gravels under observation for a number of years, and thinks that the archaeological evidence, now made available as a result of continuous supervision, may perhaps assist in the revision of published material.
The area under review measures almost two miles from east to west and a mile and a half from north to south (map, fig. 1). It may be taken as bounded on the east by the Colne Brook, one of the branches of the River Colne, and on the west by a line passing through Parsonage Farm south-west of Shreding Green, which stands, like the eastern end of Iver village in the north-east corner of the rectangle, at an altitude of 120 ft.
