Coyne notes that the western Pap is connected figuratively and literally to the eastern Pap "by a series of jagged protruding rocks set on edge, many of which are naturally-occurring, but some undoubtedly erected by hand, and known locally as the Fiacla, or teeth. These form a direct line along the 'cleavage' of the two Paps, and may mark a ceremonial route-way between the two peaks."
