Two mounds, one with a high stone content and another peaty mound to the south. They could represent field clearance or features to mark the boundary between Oare and Glenthorne, dating from the late 19th Century.

A single-storey stone built watermill was extant here in the 19th Century. It is now a dwelling. The leat is also shown on historic mapping.

The site of a corn mill has been identified, with traces of a leat still remaining.

Extensive irregular earthworks thought to relate to a shrunken village or deserted farmstead to the west of Withiel Farm.

A well preserved leat which supplied the former corn mill at Heasley Mill survives as a 1.2 metre deep cutting with a 1 metre high bank on its lower side.

A waterwheel was installed in 1886 to grind corn, attached to a barn.

A large pit or scoop recorded as an earthwork in Mill Ham Wood may be the remains of a quarry or was possibly related to water management within the woodland.

A leat or trackway was recorded during survey.

'Beasley Salmon Trap' and 'Salmon Steps' are marked on modern mapping. The site was used as a fish breeding station between c.1950 and 1980s.

There is a leat from Helebridge Weir though Rock Wood to the Weir Saw Mills.
