STRIATED ROCK SURFACE ON HARDEN MOOR, NEAR BINGLEY. 
BY E. E. GREGORY. 
{Read March 1st, 1906.) 
During an excursion from Bingley to Harden Moor, on 
Whit-Tuesday afternoon (June 13th, 1905), an interesting dis- 
<^overy was made. Some friends and myself had been searching 
for a supposed Roman road, when, quite unexpectedly, an 
exposed surface of Rough Rock bearing glacial striations was 
found. 
The striated surface is exposed for a number of yards on 
the rocks known as the " Lower Crag," and just above the 
" Crag Cottages." It is situated about 650 yards in a north- 
westerly direction from the centre of Harden village, and just 
below the 700 feet contour line. The general direction of the 
strioe is from a point about 65° W.N.W., extending towards 
E.S.E. It is interesting to note that, during its progress, the 
ice was deflected towards the west at this point ; this is proved 
by the fact that, in another position about 30 yards to the 
south-east, the striae have a direction of only 20° west of north, 
bearing to the S.S.E. (True north.) 
Note. — The exposure was again visited on June 5th, 1906, 
w^hen further evidence was found on this same crag The more 
recent record is about 40 yards north-west of the first-mentioned 
exposure, while the direction of the striae here is 50° W.N.W., 
pointing to E.S.E.
