A short stretch of ancient brushwood, laid east to west across the soft ground, appears briefly at the field surface and then simply stops, with no continuation traceable in either direction. It is the kind of relic that raises more questions than it answers.

The structure is a togher, a term for the timber trackways that Irish bog-builders laid across waterlogged ground to make passage possible. These ranged from rough bundles of branches thrown down in haste to carefully engineered plank roads; this one sits at the simpler end of that spectrum, classified as a class 3 togher. The brushwood elements were arranged lengthwise, densely packed but fragmentary by the time of survey, with individual pieces measuring between five centimetres and sixty centimetres long and only two to four centimetres in diameter. The surrounding peat is poorly humified sphagnum, the kind of soft, wet, mossy bog that preserves organic material well enough for ancient wood to survive yet makes any construction across it genuinely challenging. Among the scattered fragments, one piece was identified as willow, a wood that would have been readily available in the wet margins around such a bog. The togher lies immediately to the south-west of another recorded site in the same area, suggesting this part of Derryvella once held enough human activity to warrant crossing the bog at all, even if what remains today is only a ghost of a path going nowhere in particular.
