Extensive group of cairns on the western end of the Cefn Bryn ridge (centred on the 154m trig point). Coflein descriptions:
Little Hillend Barrow (SS47919058)
A cairn, 5.0m in diameter and 0.3-0.1m high, disturbed on the S. Thought to be sepulchral rather than a clearance feature.
Stonwold E Cairn (SS48089047)
A cairn, 7.0m in diameter and 0.2m high, set on a false crest facing N.
Stonwold E Ring Cairn (SS48169037)
A cairn-rim, or ring cairn, 14.3m in diameter, 1.5m wide and 0.2m high, mutilated to the ESE.
Cefn Bryn SW Cairn (SS48559039)
A fragmentary circular bank, 14m in diameter, 3.0m wide and 0.4m high, thought to be a cairn-rim, although possibly a ring cairn.
Cefn Bryn W Cairn (SS48589051)
A cairn, 10m in diameter and 0.7m high, having four earthfast stones, c.1.0m high, set about its perimeter.
Additional info from GGAT:
Oval mound, entirely grass-grown but set around with quartz conglomerate blocks at N (0.45x0.45m), NE (0.7x0.5m), W (0.7x0.4m) and S (0.9x0.9m); the southern block is 0.4m high, but the others are set well into the ground. N of the N stone, at a distance of 1.7m, is an orthostat 0.8x0.7m area and 0.9m high, with a scatter of small boulders in the ground around it to the N. Height difficult to gauge because of growth of gorse bushes on top. 10.6m (E-W) x 9.8m, c0.3m high.
Cefn Bryn Central Cairn II (SS48729081)
A round cairn, 6.0m in diameter and 0.7m high, along with Nprn305539, may be a sepulchral monument or a clearance element of field system Nprn305541.
Cefn Bryn Central Cairn I (SS48729067)
A round cairn, 6.5m in diameter and 0.4m high.
Cefn Bryn Field System (SS48759052)
Nine clearance heaps, 3.0-11m in diameter and 0.3-0.5m high, and a possible house site, possibly a further clearance feature, set on the summit and N facing slope of a rounded knoll. Two cairns, recorded as sepulchral, Nprns305539, 305540, may also be elements of this system.
Nant Freedown Ring Cairn (SS48849070)
A ring cairn, or cairn rim, 12.2m in diameter, 1.2-1.8m wide and 0.2m high, apparently classified as a ring cairn with a filled-in interior.
Great Cairn Ring Cairn I (SS49069072)
A fully excavated subcircular enclosure, c.10m by 9.0m, defined by a kerbed stony bank, c.2.0m wide and 0.4m high, having original entrances to the N and S, the last blocked in antiquity. Placed centrally in the enclosure was a pit containing charcoal, bone and organic material, thought to represent a token redeposition; two fire sites were noted against the inside of the bank.
Great Cairn Ring Cairn II (SS49069069)
A fully excavated subcircular enclosure, 10.8m by 10.7m overall, defined by a stoney bank, kerbed internally, 1.2-3.0m wide and 0.4-0.6m high; a small pit immediately within the NE bank was sealed by a slab; the single S entrance had been deliberately blocked and an attempt made to continue the kerbing across its site, subsequent to this the interior of the enclosure had been filled with stones.
