Image of clouds at Killary Harbor in the Republic of Ireland. Killary Harbor is a fjard that forms a natural boundry between County Mayo and County Galway in the Connemara district of western Ireland. It is one of 3 fjards in Ireland. The village of Rossroe is at the south end, near the mouth of the harbor. Lenaun is on the eastern shore. Aquaculture is a major industry with salmon farms located near Rossroe, while mussel rafts can be seen to the east toward Lenaun. As this photo attests, Connemara has some of Ireland's most dramatic scenery.
