54 BAKYNS : (GLACIAL PHENOMENA OF WIIAHFEDALE. 
As both grit and limestone occur in place in large masses 
in the district, it is of no special importance finding boulders 
of one rock lying on the other ; but I may mention that the 
limestone ridge above Fancarl House, though free from drift 
and generally bare, is strewn with boulders and blocks of coarse 
Millstone Grit. I found, too, a block of limestone on the Kinder 
Scout Grit Escarpment at the southern end of Crookrise Crags 
on Embsay Moor. 
The curious round hills forming the Millstone Grit Escarp- 
ment south of Barden, between the river Wharf e and the Pateley 
Bridge road, have limestone boulders on them. 
At Gill Bank, near Storriths, flaggy Grit, dipping at 60^ 
to the S.E., looks as if the ends of the beds had been turned 
over southward and broken. Ice moving from the north might 
have done this. 
The only other case of terminal curvature that I am ac- 
quainted with in this neighbourhood presents some difficulty. 
It occurs on the northern slope of hills forming the south part 
of Barden Moor. In a quarry near Hutchin Gill Gate the beds, 
which consist of flagstone, are dipping downhill, i.e.. to the 
north at 25° ; and the top layers are turned over, as if by a 
force acting downhill, i.e., from south to north. The slope of 
the ground does not seem to me sufficiently great for this bending 
over to be due to the " weight of the hill," as it is called. On 
the other hand, it is quite certain that the great mass of ice 
moved southward. If this bending over was caused by ice 
it must have been by quite local ice. 
As regards the drift material, it is of two sorts, well-rounded 
and bedded gravel and sand, and ordinary boulder drift. This 
latter bed is the most frequent. It cannot always be called 
boulder day, and in the higher parts of the dale but seldom so, 
for it often consists of a mass of both rounded and angular stones, 
of all shapes and sizes, with very little clayey matter at all. The 
difference, however, between it and boulder clay is mostly one 
of degree : where the drift is derived from liard, indestructible
