Notts on Cvt'c!) ^^tU. 



By H. Arnold-Bemrose, M.A., F.G.S. 



PERSONS who have travelled in the district between 

 Ambergate and Matlock are familiar with Crich Stand. 

 It is a towtr on the top of a limestone hill, in the 

 western face of which is a quarry containing large 

 blocks of rock piled confusedly one upon another. The walk 

 from Ambergate or Whatstand^^'ell is enjoyed by all who are 

 fond of the country, and the tower, from which often a splendid 

 view can be obtained, is much visited by excursionists. The 

 enjoyment is much greater if the traveller has some knowledge of 

 the way in which the rocks were formed and the surface of the 

 country attained its present shape. 



Tlie following notes are intended as a slight sketch of the 

 internal structure of Crich Hill, and to give a description of the 

 occurrence of lead ore in the toadstone. 



The district is interesting because of several landslips which have 

 occurred, and even now yawning clefts, due to the last slip, may 

 be seen from the tower. 



- The hill is composed of massive beds of mountain limestone 

 containing fossils, and is entirely surrounded by beds higher up in 

 the series. If we visit the quarry in the cliff, we see that the beds 

 are not horizontal, but that tlie bedding planes are curved. As 

 we look at a section from north to south, or at one from east to west, 

 we notice tlie bending of the strata. The dip is what is -called a 

 quaquaversal, that is, the beds have been bent so as to dip in all 

 directions from a centre, the bending having been greater in some 

 directions than in others.
