It came to light not through any planned excavation but through the ordinary work of peat-cutting, which sliced through the bog and left the feature exposed in cross-section in a peat-face nearly two metres high. What makes it stranger still is the timber at its centre: a baulk of oak incorporated into the stone spread, which predates the platform itself by more than two thousand years, making it, by the time it was laid down, already ancient.

The feature sits in the Imlagh Basin on Valentia Island, roughly 200 metres east of a prominent inselberg, an isolated rocky outcrop rising from the surrounding lowland. The platform survives as a six-metre spread of flat slabs, positioned about 0.4 metres above the base of the bog, with a thin sheet of sand running along the peat-face from its northern edge. Radiocarbon dating placed a peat sample from this level at around 6560 BP, meaning roughly 4500 BC, while the oak baulk itself returned a date of around 8910 BP, closer to 6900 BC. The researcher Mitchell, writing in 1989, interpreted the whole arrangement as a platform deliberately laid on the bog surface, with the fossil oak incorporated as a structural or perhaps incidental element. What exactly people were doing here, whether crossing boggy ground, working near water, or engaged in something less obvious, the stones do not say. What they do confirm is a sustained human presence in this corner of Kerry at a time when the island's landscape and the people moving through it would have been almost unrecognisable.
