SEC, 7.] THE CHARWAR AND KATKOL RANGE. 181 



This has been removed by denudation along the northern side so as 

 to form the scarp. 



From the very summit of Katrol and the crest of the ridge gene- 

 rallyj the rocks commence to take a southerly inclination, increasing as 

 the ground declines until the foot of the hill is reached, when it rather 

 abruptly becomes less, and in the open ground extending southward 

 to the trap boundary, the upper beds of the Jurassic series come in with 

 very gentle, but still southerly inclinations.* 



The escarpment along the northern face of this hill in this neigh- 

 Northern escarpment bourhood exposes a strong band of shales in the 



of Katrol Hill. , ^ •., i 



lower part, with calcareous beds containing belem- 

 nites, overlaid by soft thick yellow sandstones, the summits beino- 

 formed of ragged sandstones and shales with harder bands of calcareous, 

 gravelly gritj some of the latter have layers of ferruginous nodules 

 enclosing various Ammonites, Belemni1.es, and fragments of wood. Laro-e 

 specimens of Ostrea Marsliii occur in one bed of calcareous grit. 



At the north-east base of Katrol, not far from the villao-e of 

 Bowlee, the beds on the northern side of the anticlinal are well exiDosed 

 the section being as follows : — 



' In the plain near the fault are soft sandstones, variegated and 

 streaky, pinkish, with white blotches and specks ; thickly-bedded, 

 obliquely-laminated, horizontal or rolling, but close at the fault, they 

 dip steeply to south towards the vertical white sandy beds on its south 

 side. Just here there is a great crush, and the rocks are so soft and " 

 sandy that their dip or strike could hardly be traced, but a little further 

 south the beds appear more regularly.-' 



* This open ground, though declining gradually to the eastward, in which direction 

 its drainage might be expected to flow, is nevertheless crossed by several streams from north 

 to south, and instead of following the general line of denudation in the softer Jurassic 

 rocks, these have excavated for themselves deep gorges across the broad belt of traps 

 forming the Dora Hills.
