degrees would iDlough out this valley, and leave it pretty 
much in the same form as that in which we now find it, 
though perhaps a little deeper. 
The existence of Glaciers in the valleys is indicated by the 
fact, that when the Drift approaches a valley its natural north- 
and-south direction is altered, and it runs parallel with the 
direction of the valley, along its northern side ; showing that 
the Glacier which filled the valley extended so far forward, or 
was of sufficient size, to deflect the tidal current. Thus at 
Haddockstones, the Glacier which came down from the valley 
of Hebden Wood to the west, pushed itself up the opposite 
hill, and appears to have terminated a little to east of the 
place where the farm-house now stands. For immediately 
to the north of the house is a long mound running east and 
west ; the Millstone Grit which is here denuded, is worn 
smooth, and there are many large rounded blocks of Mill- 
stone Grit which seem to have been carried down from the 
upper part of the Hebden Wood Yalley and dropped here.* 
A little to the north of Ripley, there is also another long 
mound of drift running to the east, at the place where the 
valley of Cay ton Gill opens out into the wider valley of the 
Nidd ; the northern current being here again turned aside 
by the masses of ice which were in the valley of the Nidd. 
* It is from these stones that the name of the farm, Haddockstones, is 
derived.
