                                          The eastern end of the Benna Beola Mountains (The Twelve Bens), viewed across Lough Inagh from the The Twelve Bens
                                          Maamturk Mountains. The Benna Beola Mountains are composed principally of hard, resistant quartzites
                                          of Dalradian age.
