Evaluation by D Swift of ASE revealed a number of linear features, probably drainage and/or boundary ditches of post-17th century date, although they rarely produced datable material. Two of the ditches produced small quantities of Late Bronze Age and Late Iron Age pottery, although there was no conclusive evidence to suggest that this material was not residual in later features. Some small pits/postholes were also found, although none contained dating evidence. Most of the datable material was recovered from the topsoil, and was predominantly post-medieval in date.
Evaluation by F Raymond of BAS identified significant Bronze Age deposits concentrated on a plateau of land in the south-eastern part of the site, and this area was subsequently excavated. Activity commenced during the Mesolithic period, and is marked by the presence of a flint scatter from the southern part of the site. There were no concentrations of flint and no features, suggesting the principal focus, if there is one, lies or lay to the south and east. The focus of Early and Middle Bronze Age activity was located on the eastern side of the site.
Evaluation by J Robertson of SCAU prior to the construction of a park and ride facility. A series of pits was revealed, including two very large intercutting pit complexes. A prehistoric date for the features was suspected, as both Bronze Age and Iron Age pottery were present, although intrusive Roman and medieval/post-medieval pottery and tile was also recovered. Further work is planned.
Evaluation by R Lambert of SCAU prior to the construction of a series of new school buildings revealed a number of features, including a concentrated in-situ scatter of Bronze Age pottery and struck and burnt flint of considerable interest. The wider area of the site revealed further Bronze Age features such as ditches and a number of undated features of a possibly similar date. Roman activity was also recorded in the form of ditches and pits, although the concentration of features was not dense, suggesting outlying activity related to an as yet unspecified site elsewhere in the vicinity.
Watching brief by A Weale of TVAS during works on the construction of new sports pitches for the University of Surrey. A small number of postholes and pits containing pottery of a Middle–Late Bronze Age date were revealed, together with environmental evidence and charcoal fragments, which radiocarbon dating indicated was deposited around 1416–1292 BC. A medieval ditch was also recorded, running through the centre of the site. See TVAS monograph 11
Evaluation by R Lambert of SCAU revealed two late post-medieval ditches, an undated ditch, and an elongated pit or ditch. A Neolithic or Bronze Age flint tool recovered from the latter feature may be residual.
Archaeological work under the guidance of P Jones of SCAU and by N Branch of ArchS focused upon a dry valley (the hollow, as it was formerly described) visited repeatedly by Mesolithic communities that had been identified during previous evaluation at the quarry. The archaeological work consisted of geophysical survey, environmental sampling and excavation and was undertaken by professional, volunteer and student archaeologists.
Evaluation by J Vuolteenaho of MoLAS in advance of the installation of a new track revealed one area containing postholes representing either early activity, or an earlier fence alignment, and another with a small shallow feature and further postholes. Monitoring by S Davis during machine clearance around the area of the first set of postholes did not reveal any similar or associated deposits, but the concrete roof of either a basement or bunker was uncovered. Although not fully excavated, the structure was found to extend at least 2m below the present ground surface.
Continuing excavation by G Hayman of SCAU in advance of mineral extraction. Two areas were excavated in 2005. The northern of the two areas lay immediately north of the area examined in 2004 that included a large number of ditches, waterholes and numerous small pits and postholes, producing substantial quantities of pottery and struck flint, of Middle Bronze Age date. This concentration of evidence did not extend far into the 2005 area. The features were almost exclusively of Bronze Age date.
Excavation by P Riccoboni of ASE in advance of mineral working on the site. Along with some undated features, four large pits of an apparent Late Bronze Age date were interpreted as waterholes, one of which showed evidence for having been recut and re-used in the Roman period. A series of linear features of Roman date crossed the site, probably representing evidence of the remains of a field system. The foundations of a T-shaped probable corn-drying structure, again of Roman date, were also revealed.
