It does not appear on any Ordnance Survey Ireland historic maps, meaning generations of map-readers passed over this ground without any indication that something structured and deliberate had once been built here. It took aerial photography and systematic archaeological research to bring it into focus.

The earthwork sits roughly 370 metres east of Cahercorney Church and its associated graveyard, on ground that slopes down towards a stream feeding northward into the Camoge River. What makes its context particularly interesting is that it forms part of a broader monument complex in the area. The archaeologist M. J. O'Kelly recorded twelve monuments within this complex during fieldwork carried out in 1942 and 1943, publishing his findings in what became an important early survey of the region. Decades later, the Discovery Programme, a state-funded body established to carry out large-scale archaeological research across Ireland, returned to the area as part of its North Munster Project. It was through this work, specifically a study published by Grogan in 2005 and catalogued as Discovery Programme Site No. 19, that this particular feature was identified as an earthwork at all. Aerial photographs taken in January 2003, held in the Archive of the Archaeological Survey of Ireland, and orthoimages captured between 2005 and 2013, show the feature clearly as a roughly east-west aligned rectangular shape pressed into the hillside.

Because the site has not been formally field-inspected in depth, its precise character remains open. Visitors approaching the area should look for the church and graveyard as orientation points and work eastward from there across the sloping ground. The terrain is agricultural and unremarkable at ground level, which is part of what makes aerial imagery so useful here; what reads as faint and ambiguous from a field boundary can resolve into something legible from above. Anyone with access to current OSi orthoimage layers or satellite mapping applications will find the rectangular outline easier to trace than any physical marker on the ground itself.
