The Phase 3 extraction site, which is approximately 1.31 hectares in size, extends south from the existing Calverton (Burnt Stump) Quarry. The quarry is located within the parish of Daybrook and lies approximately 2km south-west of the village of Calverton. It lies north of the junction between Oxton Road (B638) and Ollerton Road (A614). The program of archaeological mitigation comprised the supervised excavation of topsoil and subsoil within the area, followed by strategic excavation and recording of archaeological remains present. Topsoil and Subsoil was excavated in spits no greater than 100mm using a 360o tracked excavator fitted with a toothless ditching bucket. Spoil was checked for artefacts including the use of a metal detector before being stored a safe distance from the excavation edge. The investigation has revealed a number of truncated ditches of probable Iron Age date which appear to be part of the wider field system identified to the north and south of the excavation area. The relatively cohesive nature of the field system as suggested by the cropmarks may be misleading as a number of the long north-east to south-west aligned linears may represent erosion features rather than ditches. The paucity of artefactual evidence reflects the site’s location outside of the more focused area of activity to the north-west. Plant macrofossils and charcoal were similarly scare but well preserved, suggesting oak and hazel were selected as fuel and wheat crop processing was undertaken close to the site.
