Oeno Island - Overlay

A bright strip of sand surrounds a pale blue lagoon and the remnants of a volcanic peak on Oeno Island. Sitting approximately 280 kilometers northwest of Pitcairn Island in the South Pacific, Oeno is a prime example of a tropical island in the middle stages of its development. Like Pitcairn, Oeno started out as a rocky volcanic peak. Over time, coral colonized the submerged edge of the island, each generation building up and out from the last until a solid ring of coral, called a fringing reef, circled the island. Sand made from the calcium-rich skeletons of coral and reef dwellers creates the brilliant white beaches seen along the outer edge of the fringing reef.
