The site does not announce itself at ground level; there is no earthwork to walk around, no obvious depression in the soil. What reveals it is a cropmark, the faint but legible signature that buried archaeology leaves on growing crops during dry summers, when roots above a filled ditch draw more moisture and grow taller or greener than those over undisturbed ground. A fosse, meaning a ditch dug as a boundary or defensive feature, traces out a circle roughly 35 metres in diameter, and a second, more fragmentary fosse appears some 20 to 30 metres further out to the north-east and east, suggesting the original enclosure may have had a wider outer boundary as well.

The evidence for all of this comes from a single aerial photograph, referenced as GB89.T.06, which captured the cropmark pattern over this field. Circular enclosures of this general type are common throughout Ireland and are associated with a broad range of uses across prehistory and the early medieval period, from farmsteads and raths to ritual or funerary sites. The double-fosse arrangement, even if only partially preserved as a cropmark, hints at something with a more elaborate layout than a simple single-ditched enclosure. The outer ditch is widely spaced relative to the inner one, which in comparable sites can indicate a boundary of some social or territorial significance rather than purely practical defence. Without excavation, the date and precise function of the Clone enclosure remain open questions, but the morphology places it firmly within a recognisable tradition of enclosed settlement or activity that shaped the Irish landscape for millennia.
