No mounds break the surface, no stones mark the ground, and a casual walker crossing this field would have no reason to suspect that beneath the grass there may be dozens of ancient barrows, the low earthen or turf-covered mounds typically raised over the dead during the Bronze Age or earlier.

The site came to light not through excavation or local tradition, but through infrastructure planning. In 1982, the Archaeology Department at University College Cork conducted a Route Selection Study on behalf of Bórd Gáis Éireann, working alongside ARUP Pipeline Engineering, to assess what might lie in the path of a proposed gas pipeline. That survey, published by Woodman in 1983, first identified what would become known as the Elton barrow cemetery. The picture grew fuller in 1986, when the Discovery Programme examined aerial photographs taken during a gas pipeline survey and a dedicated aerial photographic survey of the Bruff area. The imagery revealed as many as 37 possible barrows clustered within a remarkably compact zone measuring roughly 230 metres north to south and 300 metres east to west. A site of that density, if confirmed, would represent a significant concentration of prehistoric funerary monuments for this part of Limerick.

This is emphatically a site for those comfortable with the idea of seeing nothing at all on the ground. Current satellite imagery shows no surface remains, and the townland boundary with Ballinvana, marked by the Morningstar River to the southwest, offers the most useful geographical anchor when trying to orient yourself in the landscape. The barrows, catalogued under several reference numbers in the national Sites and Monuments Record, remain unexcavated and largely unstudied at ground level. What exists is essentially a pattern visible only from the air, or in archive photographs, waiting for the kind of detailed field investigation that infrastructure surveys rarely prompt on their own.
