The walls extend westwards up the slope, their lines faint enough to pass unremarked on the ground but legible from above in aerial photography captured between 2012 and 2018. That visibility from the air, rather than from any excavation or formal survey, is what brought them to wider attention.

The field system sits adjacent to a recorded enclosure, and together the two features suggest a patch of landscape that was once organised and worked with some deliberateness, even if the period and people behind that organisation remain unknown. Mound walls of this kind, essentially low earthen or stone-and-earth banks thrown up to define agricultural plots, are a common enough feature of the Irish countryside, but they are frequently levelled by later farming or simply absorbed into the surrounding terrain over centuries. That these walls survive at all, even in reduced form, is partly a function of the slope they occupy and its position relative to the river. It was Ros Ó Maoldúin who reported the feature to the National Monuments Service, drawing attention to what aerial imagery had preserved in two dimensions if not always on the surface itself.
