More information : A 1:1000 scale level 3 photogrammetric survey of the features visible as parch marks within the henge at Avebury was carried out by the RCHME Air Photography Unit between the 17th and 28th June 1996. The survey was carried to record a newly discovered double-ditched enclosure situated within the north-western quadrant of the henge. The enclosure is cut by the garden wall of one of the houses on the northern side of road. Faint traces of the enclosure can be discerned within the garden. The enclosure is curvilinear with four convex sides and very curved corners. Within the enclosure there appears to be a central pit. No previous record of the site is known, and it was not recorded during the early surveys of the site, indicating that it had been eroded or flattened very early on.
A morphological parallel has been suggested between this and the Neolithic oval barrow at Radley nr Abingdon (Bradley 1992 and Wilson 1982).
Photogrammetric plans were prepared with the aid of the AERIAL 4.20 rectification software published by Bradford University. The resultant plan was combined with the RCHME earthwork survey at 1:1000 scale. Also included were the parchmarks noted on the ground in 1990 by the RCHME Field survey. The plan, report and digital files are held by the RCHME (Collection UID 1057206). (1)
A discussion of the cropmark, accompanied by photographs and transcription, has been published (4). |
