Monument record HBK 018 - Possible field boundaries and enclosures of unknown date, visible as cropmarks on aerial photographs.

Complex of field boundary cropmarks, including some ice wedges. Some possible enclosures and ring ditches (S1) (S2). Probably links with HBK 007 to SE.
Possible ditched field boundaries, rectilinear enclosures and trackways are visible within a confusing pattern of geological cropmarks on aerial photographs, centred on TM 17833578 to the north of Holbrook Lodge, Holbrook. The majority of the features visible in this area appear to have a geological origins or are related to field drains. There are a number of possible rectilinear enclosures visible as partial cropmarks, including one with a possible entrance at TM 17643574 which is cut by Harkstead Road and another possible double-ditched enclosure at the opposite side of the road, centred on TM 17513567. It is possible that both these 'enclosures' could be of geological origin. Other features include a possible Post Medieval field boundary at TM 17483578, a quarry pit and possible associated hollow way at TM 18043584 and a short stretch of trackway centred on TM 17803609.
