At Boneyard Beach within Hunting Island State Park, South Carolina, United States, the first thing you notice is the trees. Then comes the question: why are bleached trunks and exposed roots scattered across the sand like a scene paused midway through collapse? Since the 1980s, Hunting Island has experienced major beach erosion, with some of the highest rates along the US East Coast—reaching up to 9 metres per year in certain areas.
