The reef itself juts above the surrounding ground, offering wide views in every direction, with the southern and western aspects particularly open to the sky. On top of it, partly swallowed by thorn bushes and encroaching vegetation, sits a cluster of structures that suggests sustained human activity across an uncertain stretch of time: at least three circular enclosures of earth and stone, a short linear bank, and two stone mounds of noticeably different sizes.

The larger of the two mounds sits on the northwest side of this grouping. It is sub-rectangular in plan, measuring roughly 7 metres east to west and 12 metres north to south, and stands about a metre in height. A central depression is visible at its summit, though by the late 1990s, when surveyor Michael Connolly recorded the site as part of a survey of the Lee Valley area, it was already heavily obscured by a thorn bush and dense scrub growth. The combination of features here, enclosures alongside mounds with a possible hollow at the centre, is consistent with a range of prehistoric and early medieval activity, though without excavation the site's precise function and date remain open questions. The limestone reef on which everything sits would have made this a naturally prominent, well-drained location, the kind of elevated ground that communities in this part of Kerry returned to repeatedly over generations.
