Despite measuring roughly 34.5 metres along its north-northwest to south-southeast axis and 15.5 metres across, it never made it onto the historic Ordnance Survey Ireland maps. It exists in the landscape but not, for a long time, in the official record.

The area around Lough Gur is one of the more densely layered prehistoric landscapes in Ireland, and this mound sits within that wider web of monuments without quite belonging to it on paper. A ringfort, which is a roughly circular enclosed settlement typical of early medieval Ireland, lies about 520 metres to the east-southeast. Two standing stones stand around 300 metres to the west-northwest, and a solitary standing stone sits just 150 metres to the southwest. It was that nearby standing stone which provided archaeologist Grogan with a reference point in 1989, placing the cairn approximately 100 metres to its east. Even so, Grogan's own thesis introduced some uncertainty, suggesting the mound might sit within Ballynagallagh townland, which made pinning down its precise location a matter of careful interpretation rather than simple measurement. The site carries the reference number LI032-040002- in the national monument record, and its existence was confirmed not through fieldwork alone but through aerial imagery, appearing as a visible mound on an Ordnance Survey orthoimage from 2005 to 2012, a DigitalGlobe image from 2011 to 2013, and on Google Earth photographs taken in March 2016, June 2018, and September 2020.

The cairn sits in open pasture, which means access is subject to the usual courtesies of farming land, and there is no formal path or signposted approach. The surrounding terrain on the south-eastern flank of Killalough Hill places it around 410 metres northeast of the Red Bog and 550 metres southeast of Lough Gur itself. Visitors already exploring the Lough Gur area, which has a heritage centre and well-maintained walking routes, might look to the satellite imagery available through Google Earth to orient themselves before heading out. The mound is subtle in the landscape rather than immediately obvious at ground level, and the adjacent standing stone to the southwest is likely the most useful landmark when searching for it on foot.
