Hadley Highstone, Barnet, North London an Arcbaeological Evaluation

The evaluation fieldwork comprised the excavation of two trenches. Trench 1, sited across the footprint of the proposed building, measured 20m long x 1.8m wide; Trench 2, located across the footprint of the proposed swimming pool, measured 10m long x 1.8m wide. Both trenches were located on cement-paved areas (Fig. 2, 7 - 8): Trenches were set out on OS National Grid co-ordinates using Leica GPS. Superficial cement/stone paving was removed by a mechanical excavator fitted with a toothed bucket. Overburden was then stripped from the trenches by means of a toothless grading bucket. All machining was conducted under archaeological supervision to the top of the natural substrate, which was the level at which archaeological features were first encountered. Records were maintained in accordance with CA Technical Manual 1: Fieldwork Recording Manual. Deposits were assessed for their palaeoenvironmental potential in accordance with CA Technical Manual 2: The Taking and Processing of Environmental and Other Samples from Archaeological Sites. No deposits were identified that required sampling. Given the absence of archaeological finds and features, the paper archive will be scanned and then discarded in accordance with Museum of London guidelines. The digital archive will be stored in CA's digital repository, where data migration and backup procedures are in place, and the integrity of the digital archive is maintained in accordance with Standard and guidance for the creation, compilation, transfer and deposition of archaeological archives (CIfA 2014b; updated October 2020). The digital archive will not be deposited with the Archaeology Data Service (ADS). A summary of information from this project, as set out in Appendix B, will be entered onto the OASIS online database of archaeological projects in Britain. In December 2021, Cotswold Archaeology carried out an archaeological evaluation of land at The Mill House, Hadley Highstone, Barnet, North London. A total of two trenches were excavated. No features or deposits of archaeological interest were observed and no artefactual material pre-dating the modern period was recovered.
