The famed Outer Banks of the Carolina coast are a slim and moving line of sand in the open Atlantic. Many travellers think they know these islands - but south of Ocracoke Inlet rises a luminous bar of sand almost sixty miles in extent, with no roads, no bridges, no hotels: the wild, remote beaches of Cape Lookout, one of the few remaining natural barrier island systems in the world. At once an exaltation and elegy, “Ribbon of Sand” profiles this seascape and the transitory islands doomed to disappear.
