Area position

The grid reference above is from SIGPAC ED50 448181 4796233 as the GPS unit was shielded by too many trees.
Below site 3912, a track leads NE through the trees past the western end of some rock outcrops. At the western end, a hole under what may be a large boulder drops down an earthy slope with a gentle draught. This needs digging out.
