A togher is a type of ancient trackway built across wet or marshy ground, typically constructed from timber planks, brushwood, and roundwood laid directly onto the bog surface or pressed into it, creating a firm enough passage for people, animals, or loaded carts to cross terrain that would otherwise be impassable. The example at Derraghan More came to light not through a targeted excavation but simply through the routine business of cutting a drain.

What the exposed face showed, across a width of roughly 4.4 metres and a thickness of 0.6 metres, was a layered and somewhat complex arrangement of wood. Recorded by Dunne in 1999, the exposure revealed two planks off-centre to the north, one laid above the other with possible brushwood packed between them, all orientated along a broadly north-northwest to south-southeast alignment that matched the direction of the drain cut itself. Towards the centre of the exposure there was further plank material, beneath which lay a denser cluster of brushwood running in several different directions, east to west, north to south, and northeast to southwest. At the southern end, a band of brushwood and roundwood about 1.2 metres wide and equally thick was recorded, its components unevenly spaced and variably orientated, suggesting either a phase of repair or a less formalised section of the structure. At the northern end, a small group of brushwood pieces was found, and below them, at a depth of 0.8 metres, heavier wood material appeared that may have been natural root matter rather than deliberately placed construction material. The distinction matters, because tease apart the built and the natural and you begin to understand how much thought and labour went into making these crossings work in the first place.
