Neither the Ordnance Survey's six-inch edition of 1840 nor the more detailed twenty-five-inch revision of 1897 shows any trace of it, which is a curious omission given how thoroughly those surveys documented the Irish landscape. The feature only came to formal attention in 1986, when aerial photography carried out as part of the Bruff survey captured it from above, and it has since been confirmed through Digital Globe orthophotos from 2011 to 2013 and a Google Earth image dated June 2018. What the cameras revealed is a linear earthwork roughly fifty metres long on its east-west axis and ten metres wide, sitting on the western edge of a steep break in slope, close to the summit of the hill.

The working interpretation, compiled by Edmond O'Donovan and uploaded to the record in September 2020, is that this may be a rock-cut path, essentially a trackway carved or worn into the bedrock, connecting the eastern terrace below to an enclosure that sits at the summit of Knockroe Hill. An enclosure in this context is a broadly defined term for a bounded area, often a ringfort or similar settlement feature, enclosed by an earthen bank or stone wall. That summit enclosure is only twenty metres to the south of the trackway. The hill itself is not an isolated monument in a quiet landscape; it is surrounded by an unusually dense cluster of archaeological features. A fort lies roughly 280 metres to the southwest, and several circular features are recorded at distances of 130 to 170 metres in various directions. The terraces on the northern, western, and southwestern flanks of the hill appear to have been intensively used over a long period, though the precise dating of the trackway itself has not been established from the available record.

The site sits in rough hillside pasture, which means the going underfoot is uneven and the earthwork itself is subtle enough that a visitor without prior knowledge of its location might easily walk past it. The panoramic views from this elevation extend to the northwest, west, and southwest, which gives some indication of why the summit and its approaches were considered worth occupying and connecting across multiple periods. The aerial photographs remain the clearest way to appreciate the full fifty-metre extent of the feature; on the ground, it reads as a low, slightly worn corridor in the slope rather than anything immediately dramatic. Cross-referencing the Bruff survey image alongside a modern satellite view is the most reliable way to orient yourself before visiting.
