Giant's Causeway is a huge deposit of columnar basalt found in County Antrim near the tip of Northern Ireland. The predominantly hexagonal-shaped columns were formed some 50 million years ago by cooling lava. This view looks inland from the edge of the Atlantic Ocean. The causeway extends a few hundred feet from the base of the cliff in the background before disappearing beneath the sea. UNESCO named Giant's Causeway a World Heritage Site in 1986. Photo taken on March 9, 2010.
