It lies precisely at the meeting point of three townlands, Loughgur, Moohane, and Kilcullane, a coincidence of boundaries that lends it an accidental significance it may never have been intended to carry. What exactly it represents remains open: from the air it appears as a dark, depressed area, the kind of shadow that suggests either a filled pond or a feature that has sunk below the surrounding ground level over centuries of slow, wet settling.

The site came to official attention not through ground survey but through the sky. During the Bruff aerial photographic survey of 1986, a photograph catalogued as Bruff 177 caught this circular anomaly lying roughly thirty metres northwest of a multi-vallate ringfort, a ringfort being a type of enclosed farmstead common in early medieval Ireland, this particular one defended by multiple banks and ditches. The earthwork appears to form part of a broader cluster of monuments in the area, including possible settlement earthworks on the southeastern side of that same ringfort. The whole complex sits about one kilometre southeast of the Carraig Aille stone forts at Lough Gur, a landscape already well known for its density of prehistoric and early medieval remains. Compiled by Edmond O'Donovan and uploaded to the national record in November 2020, the site has since been confirmed through repeated satellite and aerial imagery, appearing consistently on orthoimages captured between 2005 and 2020.

The location is accessible as part of the wider Lough Gur landscape in County Limerick, though the earthwork itself sits in low-lying, wet pastoral ground and there is no formal path to it. Visitors exploring the area around Lough Gur will find the Carraig Aille forts signposted and worth locating for context, since the earthwork lies roughly a kilometre to their southeast. The circular feature is not visible at ground level in any meaningful way; its form only resolves properly from above, which means the aerial photographs held by the Archaeological Survey of Ireland carry more of the story than anything a walk across the field will reveal. Drier months make the ground more passable, though the dark, waterlogged quality of the feature itself may be most apparent after rain.
