Centred SX 669693. Approximately 12 hectares of tinworking remains on the left bank of the River Mardle between Ryders Hill and Mitchelcombe. The workings mainly consist of alluvial streamworking remains flanking the river and two left bank tributaries with smaller, adjoining eluvially worked areas. As the slopes of Ryders Hill and Holne Ridge steepen to the north these water-worked areas become lode following openworks ending as lines and clusters of prospecting pits on the upper valley sides. Several now dry and silted leat channels traverse the hillsides supplying the workings and a well-preserved reservoir lies near the crest of Ryders Hill above the head of the River Mardle. There are no ground remains of any tinners' buildings or processing works within the surveyed area (citing Probert, S. A. J., Royal Commission on the Historical Monuments of England Field Investigation, 06/01/1997).

Approximately 25 hectares of tinworks at the head of the River Mardle, the tinworked areas fan out finger-like on the north, west and south-west slopes of the combe which forms the river catchment. The large areas of streamworks have well-defined scarps marking the extremities of the working areas, within which may be seen the characteristic evidence of streamworking, including silted water channels and spoil dumps of various shapes and layouts. The upper section of the southern tributary is, according to William Crossing, named ‘Rounder’s Hole’. Further to the west, at slightly higher altitude, several deeper cuttings represent openworks, the result of opencast lode working. The largest of these (SX 66435 69216) is named on the OS First Edition 25-inch map (surveyed 1886) as ‘Burn’s Pit’. It is up to 25 metres wide, narrowing to approximately 7 metres as it progresses westward. The overall length of the working is 315 metres. The earthwork remains of several leats can be traced across the slopes around the northern flanks of the Mardle catchment. They survive as silted, and often very faint, linear ditches with a low bank on the downslope side. Evidence of water storage survives above and southwest of the head of Burn’s Pit (SX 66130 69170), where the clear, crescentic earthwork dam of a small reservoir, has a central opening for a sluice from which a narrow diversion channel leads down to the tinwork. 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.
