The wealden is very well developed and exposed in the 

 Isle of "Wight, and forms the cliffs between Atherfield Point 

 and Compton Bay, and also appears at Sandown Bay. 

 The following section (fig. 274*) shows the relative position, 

 of the wealden and chalk with the anticlinal axis at Sandown.
