A popular Cornish beach has been stripped of all its sand by a freak high tide, leaving nothing but rocks covered in seaweed and algae. But just hours later, the change in tide deposited the golden sands back in their place. Porthleven, a holiday spot famed for its stretches of beach, was left with exposed rocks after the unusual ride swept away sand overnight. Much of the sand has disappeared from the beach which sits below the quaint seaside town, with locals describing the exposed rock as the worst they had seen in living memory. But while the sand was stripped away overnight on Wednesday January 14, it has already been deposited back in place. Porthleven is described as an 'unspoilt Cornish fishing harbour' in tourism promotions, and has just welcomed a new restaurant from celebrity chef Rick Stein. Photos from the scene show promenade steps that run down into the lush sand suddenly led to a sharp drop onto rocks. Oceanographer Alan Jorgensen, from Porthleven said he has never seen the level of sand so low in all his years in the village. He said: 'I am sure it will come back in time but I've never seen it like this before. It was a bit of a surprise to be honest.' More pics and details via Daily Mail Online.
