Excavation by D .1 Field for LTRG of a further defence section. It again showed a feature like a ditch terminal; possibly the ditch is discontinuous. A sample of the initial fill was dated to the mid 1st century AID by A.1 Clark. (206)
Site watching and rescue excavation by R J Poulton and P M G Jones for SCC and Greenham Construction Materials Ltd revealed some prehistoric features and scattered medieval pottery. In one area three interlinked ring gullies were planned and sampled and several sherds of associated pottery were recovered. This appears to have been a MIA settlement site.
Many pieces of waterlogged wood of various shapes and sizes found in deep sewer trench by Ann Watson. They were apparently sealed by a clay layer which also sealed probably prehistoric iron working sites recorded on the trench line further south at c TQ 058 599. One very large piece of wood was carefully shaped with cut rectangular holes. Preliminary dendrochronological analysis by I G Tyers suggests that C-14 dating would be of value.
Observation of gravel working by S P Dyer for SAFG located 13 wooden piles and possible IA pottery
Excavation by S P Dyer for SAFG in advance of redevelopment revealed a continuation of the multi period site at Petters Sports Field. Prehistoric worked flints, BA pottery, an IA terret (identified by the BM), a few sherds of probable IA pottery and mixed RB pottery were found in a buried river channel. The previously postulated RB road could not be located and the evidence suggested that it had not existed.
Clearance after tree loss in 1987 storm observed by D J Field, D W Williams, D G Bird and others. No finds were noted but the conditions were difficult. Geophysical survey was later carried out by S P Dyer for SCC and HBMC and various anomalies were noted. This work was followed by the excavation of three trenches by R J Poulton to provide information on which site management decisions could be based. Two trenches on sloping ground produced nothing of interest; the third, on the top of the hill, revealed IA and RB pottery and features including an IA ditch running approximately east-west.
Sixth season of excavation by G H Cole for SHAHT. Two distinct areas were examined. In the first a rectangular well was found and dated to before AD 200; it was severely disturbed by a ditch whose fill was dated cAD 200-250 and by the construction of a cesspit of cAD 1780. The second area produced worked flint dated Mesolithic/Neolithic and a barbed and tanged arrowhead. Late Iron Age pottery was found and part of a late 1st or early 2nd century AD Romanised building indicated by beam slots and said to have sand or gravel floors.
Excavation by P M G Jones for SCAU, Runnymede Borough Council and English Heritage to provide information for management of the monument. Mesolithic worked flints including cores were found. The postulated defences were sectioned and the site was confirmed as a univallate hillfort; a full detailed survey was carried out by RCHM(E). In a small trench in the interior 53 prehistoric features were found, mostly of early to middle Iron Age date, with post-holes indicating three or more building phases.
Observation and excavation by G N Hayman for SCAU and RMC (Hall Aggregates) indicated prehistoric occupation on the edge of the first area of topsoil stripping. Subsequent excavation produced evidence of BA occupation and then an Iron Age/RB site apparently occupied throughout both periods, with mid to late Iron Age domestic features, RB ditches, pits and possible farm buildings of Flavian to 4th century date.
Following evaluation two sites were excavated by G N Hayman for SCAU and Trafalgar Brookmount in advance of gravel extraction. A small Iron Age settlement site, represented mostly by large storage pits, was found on the site of the former Hollick Farm. The settlement represented by the farm itself was found to have begun in the early medieval period and continued through to the 19th century. About 750m further south a larger Iron Age site was found with a complex of features from the mid to late Iron Age; they included a large circular ditched enclosure (with a diameter of about 26m).
