Great Guana Cay Beach, Bahamas Poster

"Great Guana Cay Beach, Bahamas" by Catherine Sherman. Waves crash on limestone rocks on a beach behind Nipper's Beach Bar and Grill on Great Guana Cay in the Bahamas Islands of the Caribbean. Beautiful fluffy clouds decorate the bright blue sky. The water is many shades of blue and the sand is a lovely creamy white. Great Guana Cay, a barrier island, is a long, narrow islet, 7 miles (11 km) long, It is in the center of the Abaco Islands. It is about 8 miles from Marsh Harbour on Great Abaco Island, which has a small international airport. Approximately 150 people live on the island, mostly along the five and a half mile long stretch of beach. The Commonwealth of The Bahamas is a group of some 700 Islands and nearly 2,500 small islets or cays resting on an immense plateau of tertiary limestone that was formed between 1 and 2 million years ago. The Bahamas are not volcanic like many of the Caribbean and Pacific islands. Limestone is the only rock found in the Bahamas and is frequently worn razor sharp by the action of the wind and sea. Under water and along the shore landscapes are the result of coral growth on the plateau of limestone.The growth of coral reefs on the limestone plateau accounts for the beautiful clear waters of the Bahamas. Wave action over the centuries has created the amazing white beaches consisting of tiny fragments of coral, sea shells and limestone.
