On the summit of the mountain 10m W of the trig point. It was described by RCAHMW in 1962 thus: 'The cairn is now a stony area about 14 m in diameter, the stones piled irregularly and reaching a maximum height of 0.6 m. Some have been robbed to build a small modern shelter just to the N.E. The original limits of the cairn are not easy to determine, but in places a kerb of slabs on edge can be seen, and these indicate a diameter of 10.1 m'.
The monument now takes the form of a loose and very disrupted heap of sandstone and quartzite blocks and boulders, mainly ranging between < 0.1m and 0.5m, but with some larger. Only one of the possible kerbstones could be seen; this is sandstone and measures 0.6x0.4m; otherwise no details of the structure are now apparent. This cairn is in a very poor state of preservation, and a combination of robbing and grass growth makes it very difficult to determine where the edges are. A sheep-shelter has been constructed to the NE, presumably making use of stones removed from the cairn; there is also a rudimentary structure to the S of the cairn. c10m diameter; c0.4m high GGAT 72 Prehistoric Funerary and Ritual Sites survey 2001.

(1962/1976) On the summit of the mountain, at 410 m above O.D. The cairn is now a stony area about 14 m in diameter, the stones piled irregularly and reaching a maximum height of 0.6 m. Some have been robbed to build a small modern shelter just to the N.E. The original limits of the cairn are not easy to determine, but in places a kerb of slabs on edge can be seen, and these indicate a diameter of 10.1 m. Much of the cairn has been robbed to its base, which is revealed as a pavement of flat stones. Both pavement and kerb incorporate quartz boulders.
At 15.5 m to the S.W. a small mound with a kerb of stones looks at first sight like another cairn , but its stones lie in places on a recent humified layer and in others on a bed of lime mortar, and it must be a modern construction.
A good hollow trail descends the slope N. of the cairn in a series of sweeping zig zags.
(1972) A cairn close to bench-mark 1162 on the OS 6-inch sheet is stated in the field notebooks of Sir Cyril and Lady Fox.to have several orthostats projecting from its badly wrecked foundations. These might represent the remnants of several cists. A visit by HNS in 1970 confirmed the general terms of the statement: the cairn, about 9.2m in diameter and 0.6m high seems to have been little, if at all, disturbed duing the last thirty years; but it is grassed over and it is impossible to say, without excavation, how many cists there were and how large. Probably there were not more than three, but most of the slabs seem to be out of position and they are all titled, so that it is uncertain whether they were more than small coffers protecting urns, like those of Templeton (Pembs) and Capel Cynon (Cards).

(1977) As RCAHM (Source 06)
(1982) The surrounding area is now afforested, otherwise , no change. Five possible kerb stones could be recognised. (Source 07)
(1989) No obvious change since 1985. I was not able to locate the feature described by RCAHM as lying 15m to the SW, it may have been ploughed out. The original margin of the cairn is now very difficult to identify. (Source 11)
(1996) The remains are substantially unchanged although there has been some movement of individual stones , presumably by visitors. (Source 13)
(1996) Cairn, c10m diameter, of irregularly piled stones reaching 0.6m high. Some robbing to make modern shelter to NE. A kerb of slabs can be seen in some places but the stones are spread beyond the orginal diameter. (Source 03)
