This is the Elton barrow cemetery, one of the more quietly remarkable concentrations of funerary monuments in Munster, where the dead were laid beneath earthen or ditched mounds, known as barrows, during the Bronze Age. The particular example recorded here as Site No. 12 sits in wet pasture on a low ridge, roughly 180 metres west of a watercourse that marks the townland boundary with Knocklong West. There is nothing to see from the ground.

The site first came to notice in 1986, when an aerial photographic survey centred on Bruff picked up a cropmark suggesting a possible barrow. Cropmarks form when buried features affect the growth of grass or grain above them, making prehistoric earthworks visible from the air even after centuries of ploughing have levelled them entirely. The record was subsequently examined by the Discovery Programme, the state-funded body established in the early 1990s to investigate Irish archaeological heritage using systematic scientific methods. Their topographic survey of the field identified sixteen barrows with enough surface expression to be measured directly. A magnetometry survey of the same area, which detects subtle differences in soil magnetism caused by buried ditches and disturbed earth, pushed the number of identifiable features to twenty-two. Taken together with other recorded features, the full cemetery is understood to comprise twenty-eight barrows, as noted by Doody in 1999. A faint cropmark for Site No. 12 was still visible on a Digital Globe orthoimage taken sometime between 2011 and 2013, though current satellite imagery shows no surface remains whatsoever.

There is no formal public access to the field, which remains wet pasture in agricultural use, and nothing about the landscape announces itself as unusual. The value here is largely in the data rather than the view. The Discovery Programme's topographic survey, magnetometry results, and digital terrain model are accessible through their online archive for anyone interested in what modern remote sensing can recover from an ordinary-looking corner of County Limerick. For those who do find themselves in the area, the broader landscape around Knocklong rewards attention; the townland boundary watercourse nearby is easy to locate on a detailed map, and it places Site No. 12 at a precise and quietly telling spot on the ridge to the west.
