A number of constituent features is apparently missing from the post ring, probably as a result of total truncation. These features vary slightly in size and shape and the postulated ring they represent has a diameter of 7.5m. All of the features in this group contained similar homogeneous silty gravel fills representing general post-abandonment silting. These deposits are also included in this group." ; ; ; , , , , , , , , , , , , , , , , , , , , , , , .
