Data from an Excavation at North Portal (South Heath Cutting), Great Missenden, Buckinghamshire, 2019-2021 (HS2 Phase One)

This collection comprises a digital archive of photographs, GIS files, reports and scanned site records from an archaeological mitigation, in the form of open-area excavation, by INFRA Archaeology on land near Great Missenden and South Heath, Buckinghamshire. The excavation was targeted on the south-west side of the North Portal of the Chiltern Tunnel section of the High Speed 2 scheme, and comprised parts of two pastoral fields with a total area of approximately 2.58ha. The work was carried out between March and April 2019. The mitigation uncovered the remains of large quarry pits, large pits, postholes and ditches, and evidence of activity in the Bronze Age, Roman, Anglo-Saxon and Medieval periods. The assessment of the material recovered, and relevant corresponding data presented within this archive, has identified potential further work that could enhance the understanding of the Site.
