It was only from the air, during a 1986 aerial photographic survey centred on Bruff, that this ring-barrow was formally identified and recorded. The survey reference, Bruff 23704, marks the moment the site entered the archaeological record at all.

A ring-barrow is a low burial mound, typically of prehistoric date, defined by a surrounding circular ditch and sometimes an outer bank, the whole arrangement functioning as a monument to the dead. This particular example measures roughly 7.5 metres in external diameter, a modest but coherent form. What makes the Galboola site more interesting than a single barrow would suggest is its company. It is catalogued as one of five ring-barrows grouped in a linear cluster, each monument spaced approximately 6 metres from the next, the group orientated along a roughly northwest to southeast alignment across the same stretch of pasture ground. The cluster sits around 15 metres northeast of the townland boundary with Rootiagh, a boundary that may itself follow very old land divisions. Whether this grouping reflects a family burial ground, a community of related monuments built over successive generations, or some other deliberate arrangement is not recorded, but the linear organisation suggests it was not accidental.

Because the site does not appear on historic Ordnance Survey maps, there are no marked paths or conventional signposts to guide a visitor. The ring-barrow is detectable on orthoimagery from the 2005 to 2012 period, and was visible again on a Google Earth image taken in March 2017, though by June 2018 denser vegetation cover had begun to obscure it. That seasonal and annual variation in visibility is worth keeping in mind: the monument reads most clearly from above, and at ground level in heavy summer growth it may be difficult to distinguish from the general lie of the land. The surrounding pasture faces southwest, which means morning approaches in low autumn or winter light are likely to give the best sense of the earthwork's shallow relief. The site was compiled in the archaeological record by Edmond O'Donovan, and the record was uploaded in September 2020.
