Abstract: |
This project sought to address the need to protect and manage such significant remains by synthesising existing data and applying relatively new techniques for capturing information about the palaeotopography and the disposition of cultural deposits, with a particular focus on the location of buried areas of waterlogging/organic survival. Such deposits are most significant in terms of their archaeological potential, but also highly vulnerable to disturbance (whether direct or proximate). The project has, therefore, collected and collated together the available archaeological and geotechnical data, which were input into RockWorks so that interpolation could be undertaken between known points, and this was integrated with a digital terrain model derived from LiDAR data enabling three-dimensional surface plots and related cross-sections to be created. Where the data was densest in coverage the palaeotopography has been clearly indicated and realised for the first time in some detail, thereby defining a series of micro-basins along the course of the River Salwarpe. These constitute a significant feature of the later Pleistocene/Holocene surface, and had presumably resulted from localised subsidence due to underlying salt solution. Furthermore these were also reflected in the overlying archaeological stratigraphy both in extents and thicknesses of deposits, though not in an always straightforward correlation, while the formation of organic/waterlogged deposits did seem to have a more straightforward correlation with the newly realised palaeotopography. Recommendations are made for revising recording practice so that certain key data are collected consistently for the characterisation of a site, and then made available for this type of project in future. Above all it is now important for the HER to continue collecting the relevant information for updating and refreshing the plots produced by this project. |
