The system only came into clearer focus through LiDAR imagery, a remote-sensing technique that uses laser pulses to strip away surface vegetation and reveal subtle earthworks beneath, showing outlines that centuries of farming and overgrowth had all but erased.

The field system is understood in relation to a nearby rath, the ringfort that once anchored this piece of ground. A rath, to give the term its due, is a roughly circular enclosure defined by earthen banks and ditches, typically associated with early medieval farming settlement in Ireland. FitzPatrick, writing in 2019, identified segments of field banks on LiDAR imagery in the fields lying to the north, south, and east of the rath, as well as field boundaries that appear to extend directly off the rath itself at the south-west and north-west. A further boundary running east to west extends off the rath at the south. Taken together, these fragments suggest that the rath did not stand in isolation but sat at the centre of a working agricultural layout, its fields organised around it in a pattern that has left faint but legible traces. Whether all the boundaries belong to the same phase of activity is not certain, but the clustering around a single ringfort is consistent with how early medieval farming communities in Ireland structured and enclosed their land.
