Twenty-eight barrows, the round or oval earthen mounds raised over prehistoric burials, have been recorded within this one enclosure near Elton, and the majority of them leave no visible mark on the surface whatsoever. The grass looks like grass. The ground feels like ground. Only instruments and aircraft have revealed what lies beneath.

The site first came to attention in 1986, when an aerial photographic survey centred on Bruff captured a cropmark suggesting a possible barrow at this location, catalogued as Site No. 04 within what is now formally recorded as the Elton barrow cemetery. Cropmarks appear when buried features affect how plants grow above them, producing faint tonal differences visible from the air, particularly during dry summers. The Discovery Programme, the state-funded body established to advance the archaeological study of Ireland, later subjected the field to both topographic survey and magnetometry. Topographic work identified sixteen barrows with clear surface expression. The magnetometry survey, which measures subtle variations in the magnetic properties of subsoil to detect buried features without excavation, raised the count to twenty-two. The full tally of twenty-eight draws on all available survey methods combined. A Digital Globe orthoimage taken between 2011 and 2013 caught a faint cropmark consistent with this particular barrow, though standard satellite imagery shows nothing at ground level.

The site sits on a low ridge in wet pasture, roughly 190 metres west of a watercourse that forms the townland boundary with Knocklong West. Because there are no upstanding remains, a visit requires some preparation: the Discovery Programme's published topographic survey and magnetometry results, both accessible through their image archive, give the clearest picture of where the barrows actually lie within the field. The landscape here is quiet and agricultural, and the absence of anything obvious to look at is, in a way, the point. The most remarkable thing about Elton is precisely how thoroughly a prehistoric cemetery can disappear into an ordinary-looking field.
