An area of stream working on the upper reaches of the East Dart River and its tributaries, centred at SX614 820, covers some 14 hectares. The workings are overgrown with bog in some places, particularly around Broad Marsh on the left bank of the East Dart (centred SX617 818). On the right bank of the East Dart, opposite Broad Marsh and centred at SX6156 8180, the remains are extensive and well preserved. Here, the edge of the worked area comprises a scarp up to 2 metres high, and there are numerous channels and waste heaps resulting from the extraction and processing of the tin-bearing material. The streamworks contain the remains of eight tinner's buildings (citing Riley, H. M., Royal Commission on the Historic Monuments in England Field Investigation, 31/07/1995).)
The banks of the East Dart River have been straightened and revetted with stone to facilitate tin-working at Sandy Hole (SX 622 814) (citing a compilation of the published works of the late R Hansford Worth, and edited by G M Spooner and F S Russell 1967 Worth's Dartmoor).
