This is a stepped barrow, a form in which a central mound rises above a surrounding bank separated from it by a ditch, creating a tiered or stepped profile when viewed from the side. What makes this particular example unusual is that the monument was not simply built on top of a kame, the term for an irregular mound of sand and gravel deposited by glacial meltwater, but was shaped out of one, with the natural topography so thoroughly incorporated into the design that surveyors found it genuinely difficult to say where the glacier's work ended and the prehistoric builder's began.

When David McGuinness surveyed the monument in 2013, the details he recorded gave a sense of how carefully it had been engineered despite, or perhaps because of, its glacial substrate. The overall diameter runs to roughly 40 metres, the central mound itself nearly 19 metres across, with a noticeably flat upper surface almost 9.5 metres wide. That flat top rises up to 2.1 metres above the ditch on the western side. The whole structure slopes downward from west to east, a tilt that follows the natural inclination of the knoll beneath it, and on the eastern side the encircling bank almost disappears entirely, leaving only a low step rather than a proper earthwork. On the western side, where the bank is at its most substantial, it reaches 7.5 metres in width. Erosion on the western face of the central mound has exposed large boulders beneath the turf, and a funnel-shaped gap some 6 metres deep opens through the bank on the north-west. Whether these gaps were always present, perhaps serving as entrances, or are simply the result of centuries of weathering, remains unclear. Two further low mounds sit just outside the eastern bank, seemingly part of the same glacial feature.

The barrow does not stand alone in the townland. Four other barrows are recorded in Balgarrett, the nearest lying roughly 400 metres to the south-south-east, and from the monument's position it is possible to see Frewin Hill to the north-east and a mound-barrow on a glacial hillock at Kilpatrick more than 400 metres to the north-north-west. The clustering of burial monuments across a shared glacial terrain, each one using the natural undulations of the land as raw material, suggests a community that read the post-glacial landscape not as obstacle but as architecture already half-made.
