NHER 51577 (Monument record) - Possible pits or flint mines, linear features, and curvilinear feature

January-February 2008. Geophysical Survey.
Magetometry survey of possible aggregate extraction site (Area A).
This survey recorded several anomalies of possible archaeological origin. Six discrete positive anomalies approximately 4m in diameter have been identified as pit-like features. These are primarily located in the southwest of the field and have been interpreted as possible Prehistoric flint mines. At least 24 similar features have been identified in Area B (NHER 51578) and 2 in Area C (NHER 51579) to the east, and others have previously been identified north of the site (NHER 7798). A Neolithic chisel (NHER 7811) and Neolithic to Bronse Age flints (NHER 7812) have previously been recovered from this field. Two weak linear anomalies were also located in the southwestern portion of the site and may be associated with the pits. In addition, a fragmented curvilinear anomaly in the northern part of the survey area is located adjacent to one of the pits and may represent a small enclosure. A variety of other linear and pit-like anomalies of uncertain origin were also recorded throughout the field along with indications of the presence of ferrous material, zones of magnetic debris in the topsoil and indications of modern ploughing.
