Nineteen wetland platforms were identified during field survey of the bog, each one a deliberate construction placed within a landscape that was, by definition, unstable and waterlogged. Most were built from a combination of brushwood and roundwood, the kinds of material you might gather quickly from the surrounding woodland, but some show considerably more care: in at least two cases the brushwood was woven together, and in three others small anchoring pegs were driven in to hold the structure in place. These are not the traces of accidental deposition or flood damage. Someone built these platforms on purpose, and did so with enough craft to leave them recognisable more than two thousand years later.

Radiocarbon dating on four of the platforms has placed their construction across a remarkably long span of time. The earliest dated example falls within the Late Bronze Age, somewhere between 792 and 526 BC, while another belongs to the Iron Age, between 351 and 120 BC. That gap of several centuries suggests the bog was not visited once and abandoned but returned to across generations, perhaps by communities who understood its geography and found it useful in ways that are not entirely clear today. Wood species identified at nine of the sites include alder, ash, birch, hazel, and willow, all trees that would have grown in the wet margins around the bog itself, which points to local sourcing rather than any great effort of transport. Wetland platforms of this kind are known from other Irish bogs and are sometimes interpreted as fishing stations, fowling platforms, or simply as dry working surfaces in an otherwise impassable environment, though pinning down their precise function at any individual site remains difficult.
