having been denuded and carried away by the stream which 
runs through the gorge. 
The whole thickness of the Scars is composed of Moun- 
tain Limestone. Its base may be seen resting on the 
upturned edges of sandstone and slate, which is of Silurian 
age. They form a part of the Great Craven Fault, which 
extends in an easterly direction from Ingleton, where the 
Mountain Limestone abuts against the Coal Measures, round 
the foot of Ingleborough, along the Giggleswick and Atter- 
mine Scars, behind Settle, and thence to Malham Cove. 
Continuing still eastwards, Gordale is passed, and the 
dislocation proceeds to the south of the village of Skythorne. 
During a great portion of this distance the dislocation 
amounts to a vertical displacement of nearly 2,000 feet. The 
whole height of Ingleborough, and at least an additional 400 
or 500 feet, is required to bring the Ingleton Coal Field to 
its original position above the Millstone Grit, which forms 
the summit of the mountain. In the Malham and Gordale 
district, the displacement is probably less, the Millstone Grit 
being in juxtaposition with the Mountain Limestone ; further 
eastwards the Fault appears to have still less influence, and its 
effects gradually disappear.
