Between Land’s End and Botallack Mines is Porth Nanven, also knows as the “Dinosaur Egg Beach” because it is covered in ovoid boulders of all sizes.They boulders have been formed by the relentless pounding by the sea. But not our present sea, but a sea 120,000 years ago., the same time as the first humans made their way out of Africa and into Europe.
At that time the sea level was higher than it is now, and the stones were formed higher up. At high spring tides and storms the waves of the modern sea will wash down some of those boulders to the modern beach.
The two islands outside the beach that can be seen in a couple of my photos are called The Brisons. They are about a mile outside Porth Nanven.
