Approximately 6 hectares of tin streamworks following the course of Upper Dry Lake, an eastern tributary of the River Erme, between 385 metres and 450 metres above OD. The limit of the tinwork’s main working area is well defined by a scarp of between 1 metre and 4 metres deep running around most of the perimeter. The streamwork is between 85 metres and 32 metres wide and over 1 kilometre long. The interior working area contains the usual evidence of low linear spoil heaps, pits and channels, some of which have been reinforced by low stone revetments. The interior is also strewn with some very large granite boulders which the tinners were forced to work around and are, therefore, in situ. A large portion of the upper parts of the working are disguised by bog and rushes but a narrow channel and further workings are visible extending north. This tinwork has not been dated but , where available, documentation for tinworks elsewhere on Dartmoor would suggest a likely operational date between the 12th and 17th centuries. Three small ruined buildings survive within the confines of the tinwork (MDV116604; 116601; 116603).
