Caption: Portland Bill, Portland. Looking W.
Description: Portland Bill, Portland. Looking W. Low cliff of Portland Limestone. The gentle north to south dip of the strata in the Isle of Portland brings the Portland Limestone to sea level at the Bill. The superior hardness of roach limestone over oolitic limestone is shown by the formation of a cave by marine erosion in the softer bed, the harder bed forming the roof of the cave.
