It grades so gradually into the surrounding pasture that measuring it with any precision is awkward. Its flattened top and gently domed profile give it the look of something deliberate, something made, but what exactly it was made for remains an open question.

The ambiguity has a history to it. When the Ordnance Survey mapped this area in 1837 and 1838, the feature was not recorded at all. By 1922, however, it appeared on revised maps as an oval hachured enclosure, the hatched lines indicating raised ground or an earthwork, with dimensions suggesting an oval form roughly fifteen to twenty metres north to south and twelve to fifteen metres east to west. Since then it has been levelled, and what survives is only the ghost of that shape. An eroded section of the rise revealed the interior to be compact sandy soil with iron pan, a layer of iron-rich, compacted earth, towards the base. That stratigraphy does not settle the question of origin. The feature could have been a ringfort-style enclosure, a type of enclosed settlement common throughout early medieval Ireland, or it might be older still, a burial barrow or funerary mound from the prehistoric period. Without excavation, the distinction cannot be drawn. What is clear is that it does not stand alone: roughly ninety-five metres to the northwest, on the hilltop above it, sit a separate enclosure and a standing stone, suggesting this small landscape held some accumulated significance across time. To the west and northwest the ground opens into flat, wettish pasture, and on a clear day Nephin Mountain rises to the southwest, one of the most prominent summits in Connacht.
