The massive boulder at East Brotherfield contains one cup mark. Its measurements are 14cm wide and 6cm deep. Situated 1m above the ground the boundary marker also provides a handy marker in locating the cup.
I asked permission to park at East Silverburn, to the north east, followed the track to East Brotherfield and followed a small stream/path straight to the boulder.
There are lots of rock and rock plate so another visit needed to hopefully find some more rock art. Beautiful conditions but that would change.
