The best time to view the huge arc of Robin Hood’s Bay is at low tide when long curves of the rock strata are exposed. The Jurassic rocks of the Yorkshire coast were already old when the two of the plates that make up the earth’s surface collided causing buckling and folding of the strata, 100 million years ago. A great dome formed in Robin Hood’s Bay which has since been eroded away by glaciers and the sea to form a ‘wave cut platform’. Imagine an onion with the top cut off.
