The monument includes a tinners' cache situated on the edge of a streamwork
adjacent to Newleycombe Lake. The cache, which is beneath a large granite
boulder, survives as a deliberately constructed chamber 5.5m long, by 3.2m
wide and up to 1.4m high. The western side of the cache chamber is formed by a
drystone wall standing up to 0.5m high. The large roof boulder partly rests on
this wall and elsewhere sits on the natural subsoil. Access to the cache is
through a 1.1m wide by 0.45m high gap on the southern side of the boulder.
Leading from this entrance is a 5m long, 1.5m wide and 1m deep passage
defined on the eastern side by the scarp denoting the edge of the streamwork.
The cache is presumed to have been constructed by tinners for storage

The site of the monument is shown on the attached map extract.
It includes a 2 metre boundary around the archaeological features,
considered to be essential for the monument's support and preservation.

Reasons for Scheduling

Many small structures found within and close to tinworks are interpreted as
storage buildings. They are often referred to as caches and they survive as
very small chambers often composed of drystone walling attached to a rock
outcrop or earlier feature such as a wall; others are dug into earlier spoil
dumps. They are often circular or oval in shape and are only big enough to
hold tools or perhaps black tin (a concentrate of the cassiterite). At least
40 caches are currently recorded on Dartmoor, although given the small size of
these structures it is likely that many more await discovery. Well-preserved
examples are considered to be of national importance.
The tinners' cache 570m north east of Norsworthy Bridge survives well and
contains environmental and archaeological information for the use and
construction of the monument. This structure is considered to be an
outstanding example its class.
