Geologically, the islet of the Calf must be considered simply as a 

 prolongation of the Mull hills, separated from them by a chasm at 

 right angles to the general axis of elevation, and which corresponds,

 relative level, formed channels at Port Erin, Fleshwick and Peel. It 

 rises o-radually from the south-western extremity, the northern and

 470 feet, the highest point being at the pile near the ruins of Bushel's
