Beds of Ingleborough Hill and Moughton Fell, Yorkshire. 13 



feet. Height of some quarries of grit slate, £ mile S., 

 2090 feet;— (on Simon Fell, east side), l£ mile E. by 

 N., 1968 feet. 



C. 2. Height of the upper surface of a thin (15 to 20 feet) bed 



of limestone on Simon Fell, If mile E., 1608 feet. 

 Height of another bed of limestone near the last, 1479 

 feet. 

 3. Quarry of thin grit slate, If mile E., 1427 feet. 



D. 1. Height of the upper surface of the Dent marble bed, 



1 J mile S. by W. (in the direction of Newby), 1467 

 feet;— 1£ mile S. by E., 1368 feet;— 1* mile S.S.E., 

 1395 feet;— (on Simon Fell) Jf mile E.S.E., 1350 

 feet ; — (near Selside) 2 miles E., 1 270 feet ; — (on Park 

 Fell, part of Simon Fell,) 2 J miles N.E., 1166 feet. 



E. Height of the grauwacke (in the, Ribble under New- 



Inn Bridge near Harton), 4 J miles E.S.E., 740 feet; — 

 (near the blue slate quarries at the south-east end of 

 Moughton Fell) 4j miles S.E., 1116 feet. (This is 

 the loftiest point of the denuded grauwacke.) At 

 Hunterstyle (near Cromack) 3 miles S.E., 1047 feet; 

 — (under the huge grauwacke boulders near Austwick) 

 3| miles S.S.E., 705 feet; — (in Claphambeck, a patch 

 a little below the recently discovered cave in the lime- 

 stone,) 3 miles S. by E., about 600 feet; — (in the Greta, 

 3 miles above Ingleton,) 1 J mile N.W., about 750 feet. 



Dip of the beds above the grauwacke. — A comparison of the 

 heights of C. 1. and especially of D. 1. to the south and north 

 of the station on Ingleborough, indicates the dip of these beds 

 to be northerly. Near Newby the height of D. 1. is 1467 

 feet; and on Park Fell, 3§ miles to the N.E. 1166 feet. A 

 fall of 300 feet in a distance of 19,360 feet is equal to a dip 

 of 0° 53' 16"; but as the line of maximum depression is pro- 

 bably more to the north, its angular value will exceed 1°. — 

 (At the marble quarries east of Dent and N.N.E. of the sta- 

 tion, the height of this bed was found to be 1030 feet # .) 



Dip of the grauwacke beds. — In the Greta, 80° N.E. ; — at 

 Hunterstyle, and at the south-east end of Moughton Fell, 

 45° S. by E. ; — on Swartmoor, 80° northerly. 



Thicknesses of the beds. — A. 2. and perhaps a portion of 1. 

 about 234 feet on Ingleborough. 



B. The top lime is about 80 feet thick on Ingleborough 

 and Simon Fell. 



* Visually estimated the dip appears to be most rapid to the south of 

 the summits of Ingleborough and Whernside.
