OLIVER: MINERAL SPRINGS OF THE WEST RIDING. 343 
issue with the centric disturbances of the anticlinal displacements is 
well-known in the section of them exposed by the denuding agency 
of the Wharfe. 
3. The Skipton Group of Sulphur AYaters. 
(See diagram III). 
(a) Skipton Sulphur Water. — On the south side of Skipton, the 
Limestone shales are bent very sharply into an anticlinal axis, from 
the ridge of which the Skipton Sulphur water flows. This anticlinal 
disturbance can be distinctly traced in a south-westerly direction to 
Ray Gill. 
(h ) Broughton^ Crickle, Laugher , and Elslack Sulphur Waters. — 
This group of sulphur issues are intimately associated with the 
disturbed limestone and shales to the west of Skipton. 
The Broughton water (3^ miles W. of Skipton) rises out of the 
shales which intervene between two beds of Carboniferous Limestone 
forming the hilly ground to the north and south of them, and having 
sharp dips in opposite directions — north-west and south-east. It 
flows from the anticlinal axis, which can be traced on the one hand 
to the fine exposure on the north of Skipton, and on the other 
towards the north of Clitheroe. 
The site of Crickle Spa — marked on the Ordnance Map — occupies 
exactly the same geological position as that of Broughton, from 
which it is one mile to the S.W.* 
The sulphur water issues of Laugher about half a mile S.W. of 
Crickle, flow into a small brook which runs over the broken up 
Mountain Limestone, forming the anticlinal axis in this part. The 
water rises through the bedding on the northern side of the axis. 
The Elslack Sulphur water is also connected with the same 
disturbance of the Limestone as provides the foregoing issues : it 
does not, however, flow from a point so near the turning dips as 
these occupy, but from the bed of Limestone (or the shales below it) 
half a mile to the south of Broughton Spa, that has its fellow close 
to the latter on the opposite side of the axis. 
* ^Yhen I visited Crickle I found the basin belonging to the spa transported 
to the middle of a field. Xo doubt there are sulphur issues in the brook close by, 
but at the time I did not detect them.
