That glimpse, recorded by Timoney in 1990, revealed what road-builders in an earlier age actually did when they needed to cross wet, unstable ground: they laid down a bed of brushwood and stones, creating a firm surface over terrain that would otherwise swallow a traveller whole. These constructions are sometimes called togher roads, a term for the timber or brushwood causeways built across bogland in early medieval and prehistoric Ireland, and they are far more common beneath Irish bogs than the landscape above ground suggests.

This particular road ran roughly north to south across a shallow basin, covering a distance of around one kilometre. At its northern end stood the church of Termonkeelin, and at its southern end the church of Termon More. The word termon, in an Irish ecclesiastical context, refers to sanctuary land attached to a church or monastic site, land that was protected and often marked by boundary stones. The fact that this road appears to have linked two termon churches suggests it had a functional, possibly devotional, purpose, connecting two areas of church territory across difficult ground. The peat in the basin runs to a depth of about one and a half metres, most of it now cut away, but despite that removal neither the road surface nor any trace of it is currently visible, whether in the remaining bog or in the pasture at either end.
