These are toghers, a word from the Irish tóchar, referring to causeways or trackways laid across boggy ground to allow passage where the land would otherwise swallow a traveller whole. In Killoran townland alone, field survey identified twenty-nine of them, or at least probable examples, threading through the bog in a concentration that suggests this was once a genuinely busy crossing point in the landscape.

A survey carried out by Gowen in 1999 recorded the construction methods in considerable detail. Fifteen of the toghers were made entirely from brushwood, the simplest approach: branches and small stems laid flat to spread a walker's weight across unstable ground. The remaining examples combined brushwood with roundwood, thicker timber that would have given more substance to the surface. Three showed evidence of pegs or stakes, driven in to hold the structure in place against the slow pull of the bog. Thirteen toghers were examined for wood species, and the results revealed alder, ash, birch, elm, hazel, holly, and mountain ash, with ash and hazel appearing most frequently, likely because both were readily available and flexible enough to work quickly. A radiocarbon date obtained from one togher placed its construction somewhere between AD 1024 and 1162, placing it firmly in the early medieval period, when Ireland's bogs were navigated by monks, farmers, and traders who needed reliable routes across ground that shifted with every season.
