Excavated June/July 1934, cairn completely removed and "re-erected as nearly as possible in its former shape." There were 10 graves/cists found, containing the remains of 16 people. Remains of 2 other people were found in the cairn itself, not in the graves/cists.
The excavators found it impossible to accurately date the cairn "except to say that it belongs to the Bronze Age."
This is worth quoting extensively: "The most remarkable feature of the cairn is the fact that the ten graves contained the remains of no less than sixteen people, exclusive of course of the small traces of two others not actually in the graves. Especially noteworthy is the obvious planning of the entire mound around a central pair of graves which appear to have contained three generations of a family whose bones were probably brought from elsewhere to form the nucleus of the whole mound. It may not be too imaginative to see in this special regard for the remains of the dead, and in the accumulation of burials around the central ones some survival of the megalithic tradition which was so strongly rooted in County Clare."

150 metres north-east of the of the main cairn at Poulawack are the remains of another small burial cairn. Rising to a little over a metre, it's a robbed out ruin. Estimated diameter is about 10 metres. At the centre of the mound there are the remains of a burial chamber/cist, with some of the orthostats still in place on the east side. It's hard to guess the dimensions of this due to the infill. On a drizzly, January day we wondered who it was that pulled this mound apart and what they were looking for.
