At Tawnamore, where small-scale machine turf harvesting has stripped back layers of cutaway blanket bog, three fragments of stone walling have begun to surface, the remnants of a pre-bog landscape that was buried long before anyone thought to record it.

The site sits on a north-south ridge whose eastern flank drops into the Easkey River valley, and it was formally listed as a pre-bog field system in the Record of Monuments and Places in 1995, though no description or supporting information was attached at that time. When the area was inspected in 2014, what emerged was fragmentary but suggestive. The most legible feature is a curving arc of densely packed stones, between 0.7 and 1 metre wide, that can be followed for roughly 19 to 20 metres on a roughly north-northwest to south-southeast alignment; a change in the colour of the low heather growing above it, a cropmark of sorts, helps trace its course. Some 35 metres to the southeast, a second concentration of stones extends for only 4 to 5 metres before being bisected by a later peat bank. A third fragment, barely protruding from the bog surface, lies just 10 metres further east and runs for around 3 metres. Together they cover a small area, but their precise relationship to one another remains unclear, and the original layout of the field system cannot be reconstructed from what survives.

Pre-bog field systems of this kind, walls and enclosures that were already ancient when the blanket bog began to form over them, are known from various parts of the west of Ireland, most famously at Céide Fields in Mayo, where a whole Neolithic landscape was preserved beneath the peat. Tawnamore offers nothing so dramatic, but its quiet incompleteness is part of what makes it interesting. The bog has not finished retreating, and what lies beneath may yet clarify what these scattered stones once divided.
