There are two cairns here. The northern one (ST10489223) is as described in Carl’s fieldnote.
The southern one (ST10509215) is smaller. Coflein:
On open moorland, is a grass and bracken covered stony mound, diameter 7.0m, height 0.6m. A probable cairn. Discovered during field investigation (OS).
There is also a recumbent stone (natural?) lying a little to the north of the northern cairn, as the ground starts to slope away.
