Oliver's Mount is an outlying spur of the calcareous range. 

 Between Scarborough and Filey the highest point of the cliff is 

 under 300 feet above high- water mark. From Scarborough as far 

 as Ewe Nab the Upper Sandstones of the Lower Oolite form 

 the greater part of the cliff, and the calcareous band may be 

 seen beneath them in several places. By a landslip in Cayton 

 Bay we have the Oxford Clay brought down to the shore and 

 over it there is a cliff of Calcareous Gritstone. North of the 

 Redcliff fault we have all the beds of the Lower Oolite from the 



Jan. 1839.
