Reference: Mark Fenlon, who kindly supplied the list of DNPA stones that was obtained from Tim Russell of Dartmoor National Park Authority.
Reference: Thanks to Tim Jenkinson for details on this. There is supposed to be a benchmark on the west face, although it could not be seen. Perhaps that small indentation on the top is where there was once a bolt (rivet)?
