The term earthwork covers a broad range of man-made or modified ground features, from the raised banks of enclosures and field boundaries to the remnants of ringforts, burial mounds, or defensive ditches. Without more detail, the feature at Cloona belongs to that quietly significant category of places that have been noticed and catalogued, yet whose story remains, for now, incomplete.

What can be said is that the site exists within a county that holds an extraordinary density of early medieval and prehistoric monuments, from the limestone karst of the Burren to the more pastoral lowlands where earthworks of various periods survive as low ridges or cropmark patterns in fields. Clare's archaeology spans millennia, and an earthwork in a townland like Cloona might represent almost anything, a field enclosure from the early medieval period, a boundary feature of considerable age, or something older still. The formal record exists, but the descriptive content that would allow a fuller picture has not yet been made available.
