What survives of it amounts to two oak planks, lying roughly fifty metres apart, oriented in the same north-west to south-east direction as though still pointing the way. Together they represent what may be a togher, the Irish term for a timber trackway laid across bogland to allow people, animals, and goods to cross ground that would otherwise be impassable. It is not a grand thing, and it does not look like much on paper. That, in a sense, is part of what makes it interesting.

The two planks were observed on the field surface in Derryvella bog. The south-eastern one is a fragmented split oak plank, just under a metre long and roughly thirteen centimetres wide, already in poor condition from machine damage by the time it was recorded. The north-western plank is slightly larger, around a metre long and twenty-four centimetres wide, and similarly degraded where it had been exposed to machinery. Beneath both planks, the underlying peat is a moderately humified sphagnum moss peat, the kind that builds up slowly over centuries in waterlogged, oxygen-poor conditions, and which is precisely why timber can survive within it for so long. The calluna, or heather, inclusions in the peat suggest the bog had drier phases at some point in its history. The full extent of the possible trackway runs to approximately fifty metres, though only these two surface planks were documented.
