Wheal Compton Dartmoor Central, Devon. OS Grid SX672723
Lat/long 1830 Tin Shafts
Wheal Cumpston (Wheal Combestone; Steepehill), Dartmeet, Southern Dartmoor, Dartmoor & Teign Valley District, Devon, England, UK
A small but ancient tin mine located within Combestone Woods, half a mile down river from Dartmeet on the western side of the river. All that remains is an overgrown gulley and pits encorporating a ruined Tinner's hut and an adit (drive) below the main gulley at the bottom of the hill.
I have found no evidence of CUMPSTONs being connected with this mine but would welcome any information.
