34 BAKER S NORTH YORKSHIRE. 



beneath the surface, but as we pass towards the north they rise 

 again, and soon the Cornbrash terminates, and for some distance 

 the Upper Estuarine, with a mass of Boulder Clay over them, 

 make up the whole of the cliff, which here is under 200 feet in 

 altitude. At Cloughton Wyke w^e have on the top of the cliff 

 thick beds of block sandstone belonging to the lower part of the 

 Upper Estuarines, beneath it a considerable thickness of shale 

 with ironstone balls. Then comes the Grey Limestone series, 

 here consisting of 6 feet of nodular shaly limestone full of 

 shells, lyo. feet of shale, again a bed of nodular shaly limestone 

 full of shells, 2^ feet of shale, then soft calcareous layers with 

 shells, and lowest of all the solid subcalcareous sandstone of the 

 third set of beds, with a few fossils and accompanied by ironstone 

 and calcareous shale. The strata still continue to rise towards 

 the north and soon the Middle Estuarine, Millepore and Lower 

 Estuarine beds make their appearance, with a coal seam about a 

 foot in thickness in the first. At Hayburn Wyke there are 

 considerable marks of dislocation. From this point to the High 

 Peak the cliffs rise in altitude from 296 to 585 feet above high 

 water mark. In this long line of magnificent precipices we have 

 very nearly the whole of this series of strata exposed so as to 

 allow of ready examination, for although opposite Staintondale 

 a landslip hides the lower part, yet by combining what is seen 

 on the north and south of it we obtain an excellent section as 

 follows, viz. ; — 



6, Upper Estuarines, 40 feet : carbonaceous gritstone with 

 black shales and carbonised wood. This is quarried at the edge 

 of the cliff. 



5. Sca7-borough (or Grey) Limestoties (marine), 30 feet : shelly 

 limestone with Beletnnites giganteus, and shales. 



4. Middle Estuarines^ 120 feet: sandstone and shale beds 

 in numerous alternations, with fossil plants and traces of coal. 



3. Millepo re-bed (marine), i o feet. 



2. Lower Estuari7ies, 2,20 {ett: 60 feet chiefly thick sand- 

 stone : 200 feet thick shales and thin sandstones in numerous
