A boundary cairn, a pile of stones set to mark the edge of one townland and the beginning of another, was recorded here at the meeting of Knocknagalty and Drumleagh. Today, depending on how you look for it, it may as well not exist at all.

Boundary cairns are among the more functional monuments in the Irish landscape, placed not for burial or ceremony but for the practical business of knowing whose ground you stood on. This particular example was catalogued as part of a cluster; two related cairns, recorded under references LI050-033 and LI050-034, lie 80 metres and 260 metres to the east. The site itself was noted as a small circular mound on the Cassini edition of the Ordnance Survey six-inch map, and by 1897 the 25-inch edition labelled it simply as a 'Mound', which suggests that even by then its original character was not entirely clear to surveyors. When aerial and satellite imagery was assessed, most recently through Digital Globe and Google Earth orthoimages taken between 2011 and 2013, no surface remains were visible at all. The ground has either absorbed or obscured whatever stones once marked this division in the land.

The site sits in rough pasture on the townland boundary, which means the terrain is not particularly welcoming. The Galty ridge is exposed walking country, and the precise location of the cairn falls between named summits rather than on any obvious path or waymarked route. Anyone with a serious interest in the site would do well to cross-reference the Ordnance Survey mapping editions mentioned in the record before setting out, as the absence of visible surface remains means there is little to orient yourself by once on the ground. The wider ridge walk, which takes in Galtymore itself, is well documented among hill walkers and gives a reasonable approach to the general area. The companion cairns to the east at least confirm that this was once a deliberately marked boundary line, even if the stones themselves have long since disappeared into the hill.
