- Found it
My last cache of the day on a circular walk via the East Dart, Ladehill Outcrop, Grey Wethers and Stannon Tor. From my notes on GC dot com I had three of the four pieces of information I required. This gave me a north and a south limit and I was going to try walking along a line in the hope I spotted the hide. A chance look at the related opencache revealed the piece of information I was missing and this meant I could avoid all the gorse and bog in this area to go straight to the hide.
