Abstract: |
Geophysical survey was undertaken over a group of barrows, near Over and Willingham, Cambridgeshire, in September 1996. The barrows lay immediately adjacent to an area threatened by gravel extraction and fell within the limits of a long-term hydrological
monitoring project that aimed to examine the effects of large-scale mineral extraction on an apparently well preserved and potentially
waterlogged archaeological landscape over a period of up to 25 years by combining archaeological excavation and prospection with long-term environmental monitoring. The main aim of the geophysical survey was to elucidate as much information as possible
relating to the barrows by revealing their locations, size and number of encircling ditches as well as attempting to detect any surviving internal features. In addition, it was hoped that any archaeological features present in the spaces between the barrows might be identified. Earth resistance and limited magnetometer surveys were undertaken with resistance proving to be the more effective technique in the local fenland site conditions for mapping the remains of the barrows. The barrows are partly protected by alluvium, although the crowns of the barrow mounds have been spread by ploughing. The northernmost mound stands to a height of 0.5m, as does its neighbour 40m to the south west. The most substantial remains are those of the southernmost mound reaching up to 1m high. The mounds 60m and 150m to the north west are both approximately 0.3m high. Although the diameters of the upstanding remains vary due to the effects of arable cultivation, the geophysical survey undertaken in 1996 demonstrates that the central mounds all originally measured just under 20m in diameter. Anomalies detected by the survey within the northern and westernmost mounds may indicate the presence of internal structures. Ditches were identified surrounding four of the mounds, which are thought to measure up to 4m wide. Surrounding the barrows the geophysical survey detected a network of linear ditches, which seems to respect the mounds and is probably of late Bronze Age date. The ditches form small paddocks with clearly visible entrances, in which the barrows occupy marginal positions. In between the barrows is also a scatter of anomalies that may represent archaeological features, such as pits. |
