The exposed section measured just over half a metre wide and barely four centimetres thick, yet within that compressed layer lay around twenty-five small pieces of timber, each no wider than a finger and only a few centimetres long. Only the tips of the pieces survived, preserved by the anaerobic conditions of the surrounding peat, which shuts out the oxygen that would otherwise allow organic material to decay.

The uniformity and density of the brushwood prompted initial consideration that it might be the end of a hurdle, a woven panel of interlaced rods used in early Ireland for fencing, trackways, and other practical purposes in boggy terrain. Hurdles typically show evidence of upright stakes, known as sails, threaded through with more flexible rods, but no such worked or structural pieces were found here. That absence shifted the interpretation: what survives at Corragarrow is more likely the remains of a peatland platform, a laid surface of brushwood intended to support activity or movement across ground too soft to bear weight otherwise. Such structures are a recurring feature of Irish bogland archaeology, constructed by communities who worked, travelled, or lived alongside these waterlogged landscapes for thousands of years. The find was recorded by Dunne in 1999 and assigned the reference 99BG0011A.
