Measuring roughly four metres east to west and three and a half metres north to south, it is the kind of cairn, a deliberate accumulation of stones used variously across prehistory for burial, marking, or territorial signalling, that could easily be walked past without a second thought. What makes it worth pausing over is the company it keeps.

Keegan, writing in 2016, recorded this cairn as one of several distributed across the Termon plateau, which is itself covered by an extensive ancient field system. Another cairn lies around seventy metres to the south-west, and further examples are scattered across the plateau beyond that. The field system and the cairns together suggest a landscape that was once actively organised and inhabited, its upper reaches divided, marked, and used in ways that are no longer fully legible. The Termon plateau, with this concentration of remains, reads less like an empty upland and more like a place that once had considerable meaning for whoever lived and worked across it.
