Two boundary stones are marked on historic and modern (2013) mapping. They are likely to be part of a larger group that subdivide the Down.

A post-medieval field boundary is visible as an earthwork on aerial photographs. It is not shown on the 1st Edition Ordnance Survey map and may represent part of the original enclosure of this area of land.

A small post-medieval extractive pit is visible on aerial photographs as an earthwork. It is likely to be an area of small scale stone quarrying which has been backfilled.

A series of possible craters are visible on aerial photographs and likely to be related to the Second World War military activity in this area.

The earthwork remains of a probable post-medieval field boundary are visible on aerial photographs. It is most likely to represent part of the 19th Century enclosure of Holdstone Down and Girt Down which was later abandoned.

Two lines of small craters or mounds are visible on aerial photographs at the northern extent of Holdstone Down, close to the cliff edge.

The shaft may be one referred to as Shacrey Shaft, probably part of the silver lead workings associated with West Challacombe Mine. It was not located in 1993 and may be hidden by cliff erosion.

A cropmark, visible on aerial photographs taken in 1946, has been interpreted as the possible remains of a farmstead. There was no trace on the ground in 1993.

A group of alleged lynchets directly above the cliff east of Little Hangman, noted on aerial photographs taken in 1946, are natural shelves formed by the stratification of the underlying rock.

Lynchets visible as cropmarks above Blackstone Beach were identified from aerial photographs taken in 1956. Field investigation in 1993 could not locate them and they are assumed to have been natural features.
