Observation of initial phases of gravel extraction by S P Dyer for SCC and Greenham Construction Materials Ltd with no result.
Observation and excavation by P M G Jones for SCAU and RMC (Reservoir Aggregates) in advance of gravel extraction located evidence for Neolithic occupation.
Further excavation by P M G Jones for SCAU and SCC (Property Services Department) confirmed the medieval date of 'Caesar's Camp' (formerly supposed to be RB), although its function is still obscure. It was probably constructed in the 12th century and backfilled by the 14th. Traces of BA settlement were located including ditches and a pit. (report in SyAC 94)
Observation of gravel extraction by S P Dyer for SCAU and Greenham Construction Materials Ltd revealed the blade end of a very large polished flint axe.
Excavation by G N Hayman for SCAU and Greenham Construction Materials Ltd in advance of gravel extraction showed that an earthwork known from aerial photographs was post-medieval but located nearby evidence for an enclosure of EBA date.
Monitoring of topsoil stripping for gravel extraction by S P Dyer for SCAU and Reservoir Aggregates Ltd. No features of archaeological interest were revealed. (265)
Evaluation in advance of gravel extraction by G N Hayman for SCAU and Greenham Construction Materials Ltd revealed two concentrations of prehistoric features, including pits and a probable boundary ditch. The fill of these produced BA pottery, but a couple of the pits also contained concentrations of cremated human bone. (262)
Continued monitoring and evaluation in advance of gravel extraction by G N Hayman for SCAU, Greenham Construction Materials Ltd and Thames Water led to the discovery of prehistoric material. Subsequent excavation produced features and finds suggestive of a small farmstead, occupied from the end of the Neolithic into the early BA. (261)
Excavation by J J Chapman for SAFG in advance of redevelopment revealed traces of a 2nd/3rd century ditch.
Excavation by G N Hayman for SCAU and Greenham Construction Materials Ltd of the enclosure identified during evaluation in 1990. The enclosure was found to be rectangular, bounded by a ditch on three sides with a small entrance in both the north and east sides. Within this enclosure was found a ditched feature, 10 metres square, roughly central to which was a large near-vertical sided, flat-bottomed pit. Finds from these features were relatively few, but consisted of struck flints and pot sherds, which indicated an early to middle BA date
