It measures roughly twelve metres across and stands no more than seventy centimetres high, its circular outline defined by large stones beneath the turf. What tips it from merely unremarkable to genuinely curious is a detail offered by the landowner: in snow, a straight line becomes visible extending to the north-east from the monument, suggesting some alignment or associated feature that is otherwise invisible in ordinary conditions.

The mound came to wider attention only in October 2021, when Aidan Harte, Project Co-ordinator of the Leitrim Sweathouse Project, reported it as an unrecorded site. It lies on the crest of a north-south ridge about ninety metres east of the Eslin River, which flows southward through the surrounding farmland. Local memory of the place, however, reaches further back. The Schools Manuscripts Collection, a vast archive of folklore gathered by schoolchildren across Ireland in the late 1930s, contains a note on this very spot: that in the townland of Cavan there is a mound or cairn, and that local belief held it to cover either treasures or urns containing human remains. A cairn, in this context, typically refers to a mound of stones raised over a burial, often of prehistoric date. Whether that tradition preserves a genuine memory of what lies beneath, or simply reflects the kind of story that tends to attach itself to any unexplained earthwork, cannot be said without excavation.

The site sits on working farmland, so any visit would require the landowner's permission. Those who do make their way there in winter, after a fresh snowfall, might find themselves looking at the landscape differently, watching for that straight line extending away to the north-east.
