Summary
Approximately 32 hectares of streamworking remains flank the left bank of the River Erme and the floodplains of three of its tributaries, Blacklane Brook, Dry Lake and Red Lake. Several related blowing houses, tinners huts and leats recorded (see related records). Little deposition or disturbance has occurred since the abandonment of these workings and as a consequence they constitute some of the clearest and best preserved examples of this type of tin extraction on Dartmoor.

Some way down stream are the remains of a tinners hut. There are two ruined blowing houses on the "Yealm", one on each side of the river. There are remains of tinners working along the Erme.

Good examples of tin streaming remains consisting of parallel ridges of waste material are widespread in this area. Probably relating to the period before 1600.

(10/11/1994) [Part of] Approximately 32ha of streamworking remains flank the left bank of the River Erme and the floodplains of three of its tributaries, Blacklane Brook, Dry Lake and Red Lake. The former workings are marked by the characteristic spoil heaps and water channels enclosed by a sharply cut cliff. In several places, most noticeably on the Blacklane Brook between SX 63066793 and SX 63026720 and at SX 63466655 on Dry Lake, are large bands of parallel linear spoil heaps most of which are revetted through at least half of the worked area appears to have been more randomly exploited or reworked at a later date. The cliffs marking their edges also remain well preserved and range in height from around 1.0m to 3.5m. Several leats (Monument HOB UID 1063683, 1063691 and 1063696) formerly feeding the sides of the streamworkings and openworks that extend up the various valley sides are visible on the surrounding hillsides and unexploited areas of floodplain.
The remains of one (Monument HOB UID 441565), possibly two (Monument HOB UID 1063737) blowing houses, seven identifiable tinners huts (Monument HOB UIDs 441565, 441635, 441638, 1063732, 1063742 and 1063753) and two other structures (Monument HOB UIDs 1063422 and 1063734) are visible within the investigated area of streamworks.
Little deposition or disturbance has occurred since the abandonment of these workings and as a consequence they constitute some of the clearest and best preserved examples of this type of tin extraction on Dartmoor.
