XXXVI. Geological and Miner alogical Survey of Part of the 

 Yorkshire Coast. Drawn up by the Rev. Gko. Yov^g from 

 Materials chiefiy furnished by Mr. J. Bird*. 



J. HE mountainous tract, bounded by the plain of Cleveland on 

 the north and west, and the vale of Pickering on the south, may 

 be distinguished into four parallel ridges of hills, running from 

 east to west. The first commences with the lofty cliffs at Boul- 

 by, and terminates at the western extremity of Barnaby moor. 

 The highest parts of this ridge are Easington heights, Huntcliff, 

 Burleigh moor, and Eston Nabb, which rise from 600 to 800 

 feet above the level of the sea. The second ridge, which com- 

 prehends Che moors of Aislaby and Danby, and extends to High 

 CliflF Nabb and Rosebury, is considerably more elevated; Danby 

 beacon being 966 feet high, and Rosebury Topping 1022 feet. 

 This ridge is separated from the former by the vales of Guisbo- 

 rough, Skelton, Lofthouse, and Dalehouse. On the south, the 

 vales of Kildale, Common Dale, and the Esk, part it from the 

 third ridge which is much more extensive, and forms the central 

 and most elevated part of our moors; beginning at Peak and the 

 Fyling hills, and proceeding westward by Lilia cross, Silhoue, 

 Cock Heads, and Ralph cross, to Burton Head, Cold moor, and 

 Cranimoor. The western part of this ridge is by far the most lofty, 

 the heights at Cock Heads and Ralph cross being 1400 feet above 

 the level of the sea. Burton Headf 1485, and Cranimoor up- 

 wards of 1500. A spectator on Cranimoor can observe the sea 

 over the summit of Rosebury. This ridge is of great breadth, es- 

 pecially in the middle, where it reaches from Danby dale to the 

 valley at Lestingham and Hutton. Immediately beyond the lat- 

 ter valley we find some of the hills of the fourth ridge, which 

 takes its rise near Scarborough, and includes the hills ofSeamer, 

 Silphoue, Langdale, Crosscliff, Saltergate, Cawthorn, Spaunton, 

 Gillimoor, &;c. extending to the vale of the Rye. In point of

 Colonel has committed an error in regard to the angle taken at Burleigh
