Coflein indicates that there are/were five cairns here, as well as a pillow mound which appears to be one of the “cairns” marked on the OS 1/25000. North-south descriptions:
Cairn IV (ST11066604)
Nothing that I could see on the ground, Coflein has:
This is one of a group of mounds excavated in the nineteenth century, when it was found to be encircled by a shallow ditch. The only small finds were two pieces chert and several horse teeth.
Cairn I (ST11046603)
A cairn, excavated in the 19thC, now comprises an annular bank measuring 7m in overall diameter, 1.5m internally, with a height of 0.5m. It is eroded on its W side.
Cairn III (ST11066600)
The cairn exists as a kerb of stones, most noticeably on the S and W where the kerb is 0.2m high, enclosing an an area of gravel and small stones measuring 5.9m (N-S) by 4.8m. It is spread on the N side and eroded to a height of 0.1m on the E.
Cairn II (ST11066598)
Described in 1873 as the most southerly of three mounds, it was partly removed to make a platform while the remainder of the stones were subsequently removed to make a flagstaff mound.
Cairn V (ST11096596)
Didn’t see this one either.
A small mound, 3m in diameter, excavated in late 19thC without result.

Pillow mound (marked as “cairn” at ST11036612)
A grassy earthen mound measuring 14m (E-W) by 9.1m and 0.5m high. It is surrounded by a 0.3m deep ditch which is completely eroded on the E; its inward-facing scarp is 2.3m wide on the N & S
