40 baker's north Yorkshire. 



Oxford Clay, 25 feet of the Kelloways Sandstone, with 55 feet of 

 the beds of the Lower Oolite series beneath them. At Redcliff, 

 by the 140 feet dislocation of which we have already spoken, we 

 have on the north the Kelloways band brought nearly down to 

 the shore and the whole series shewn in the cliff of 285 feet as 

 high as the lower part of the Lower Calcareous Gritstone. By the 

 landslip in Cayton Bay we have the Oxford Clay brought down 

 to the shore-level, with a cliff of Lower Calcareous Gritstone over 

 it. Between the White Nab and Scarborough only the Kelloways 

 sandstone is seen, and this caps the Lower Oolite only in one 

 particular locality. In the Castle hill at Scarborough we have all the 

 beds from the Coralline Oolite, 40 feet in thickness, downwards, 

 with a remarkable dislocation on the northern face of the hill by 

 which a narrow band is uplifted so that the Kelloways Sandstone 

 is brought to a level with the lower part of the Lower Calcareous 

 Gritstone on either side of it. At the pier the Kelloways Sand- 

 stone occupies the shore, but on the north of the Castle hill, 

 except in the uplifted portion, we have the Oxford Clay 135 feet 

 in thickness. In the low cliffs on the north of Scarborough 

 the beds rise gradually, and before we reach Scalby the series 

 disappears, and is not again seen. 



The Upper Calcareous Gritstone covers the Coralline Oolite in 

 various inland localities, as at Silpho Brow near Hackness, and 

 in several places in the low ground about Kirby-moorside, 

 Helmsley and Ampleforth. The Coralline Oolite and Lower 

 Calcareous Gritstone form everywhere the surface and upper 

 levels of the range of moorlands, often passing one into the 

 other by gradual stages of transition. At the western extremity 

 of the range we have the Calcareous Gritstone well exhibited 

 in the conspicuous precipices of Whitstoncliff, Boltby Scar and 

 Rolston Scar, at the first mentioned station forming a per- 

 pendicular cliff just 100 feet in depth. Here the Oxford Clay 

 below the cliffs is considerably thinner than in the coast sections ; 

 but the Kelloways Sandstone may be traced from Scarborough 

 along the northern escarpment of the range to the Thirsk tract
