250 FOX-STRANGWAYS: COAST BETWEEN REDCAR AND SCARBOROUGH. 
Hood's Bay. The spifiatus and 77iargar{tatHS-heds are well seen at 
Hawsker Bottoms, and it is interesting to observe the change in 
character which has taken place between here and the sections further 
north. The great ironstone seams of Cleveland have nearly disap- 
peared, and are only represented by narrow^ bands which are difficult 
to correlate with these well known beds. 
In Robin Hood's Bay the strata are thrown up by an anticlinal 
axis, and the lower beds of the Lias are again exposed in the extensive 
scars which may be examined at low water. These scars are composed 
of the several zones of the Lower Lias, which, from the quaquaversal 
dip of the beds, form a series of semicircular bands round the centre 
of the bay. The lowest beds of the Lias (the zone of A7?i. planorhis) 
are not seen here, but their presence is proved by blocks containing 
the characteristic ammonite being occasionally washed up by the 
waves. The Biicklcuidi-heds occupy the centre of the bay, being 
succeeded by the oxi/notus-heds which form a semicircle partly covered 
by sand between Bay Town and Peak ; these in their turn are 
covered by the Ja7neso7ii-heds at either end of the bay, above which 
the caprico7'nus-heds rise in the cliff. At low water these several 
zones may be followed by the eye for some distance. 
On the south side of the Bay the Peak cliffs rise to an altitude 
of over 600 feet, and exhibit a magnificent section of the lower part 
of the Inferior Oolite and of the upper part of the Lias. The chief 
point of interest here is the large fault having a throw of about 200 
feet, which has brought the sandy beds of the Middle Lias against 
the Inferior Oolite, and which is clearly seen in the cliff where the 
footpath descends at this spot. 
A short distance further south we come to the little indentation 
of Blea Wyke, where the base of the Oolite reaches the shore, and 
where the unique section of the sandy passage beds between that 
formation and the Lias occurs. The Blea Wyke Beds have been 
referred by some authors to the Lias, by others to the Inferior Oolite ; 
they have a thickness of about 50 feet or rather more, and this is the 
only place they are known for certain to occur, their presence inland 
being doubtful. The Dogger, the marine bed at the base of the 
Inferior Oolite, is here a ferruginous sandstone with a peculiar
