Twenty-eight barrows, the rounded earthen mounds, often ringed by a ditch, that prehistoric communities raised over their dead, have been recorded within the one field at Elton. The particular barrow known as Site No. 14 sits in wet pasture on a low ridge, roughly 160 metres west of a watercourse that marks the townland boundary with Knocklong West. At ground level, no surface remains are visible at all.

The sheer density of monuments here only became apparent through systematic survey work carried out by the Discovery Programme, an Irish archaeological research body established in the 1990s to bring modern remote-sensing and surveying techniques to bear on the Irish landscape. When researchers examined aerial photography from the Bruff survey, Site No. 14 was flagged as a potential barrow. A topographic survey of the field made sixteen barrows clearly legible in the terrain. A magnetometry survey, which detects subtle variations in the magnetic properties of the soil caused by ancient disturbance, identified twenty-two. Taken together, the surveys outlined a barrow cemetery of unusual scale. The site is referenced in Doody's 1999 study of the area, which recorded the full complement of twenty-eight monuments. A faint cropmark, the ghostly outline that buried features sometimes leave on growing vegetation during dry summers, was visible on a Digital Globe orthoimage taken between 2011 and 2013, offering one of the few visual traces of Site No. 14 from above.

The field lies close to the Knocklong West townland boundary in south County Limerick, and the broader Elton barrow cemetery carries the record number LI040-229002. Because there are no upstanding remains visible from the ground, a visit rewards those who come with the survey images in hand rather than any expectation of dramatic earthworks. The Discovery Programme's topographic survey, magnetometry results, and digital terrain model are accessible through their image archive, and comparing those datasets against the apparently ordinary pasture in front of you gives the site its particular quality. The monuments are entirely present; they are simply invisible to the unaided eye.
