Where most wooden objects from early Irish life rotted away centuries ago, the anaerobic, acidic conditions of a raised bog can hold wood in near-perfect condition for thousands of years.

What was recorded here is an extensive band of brushwood, nearly two metres wide and roughly half a metre thick, composed of slender rods and branches between two and five centimetres in diameter, with two heavier roundwood timbers of seven to eight centimetres running through the mass. The whole arrangement is oriented northeast to southwest. Peatland platforms of this general type were typically constructed to provide a stable working or walking surface over soft or waterlogged ground, the builders laying down layers of cut wood much as a modern engineer might use a raft foundation. The exposed dimensions suggest this is only a fragment of what may originally have been a more extensive structure, the rest still buried or lost to peat cutting.
