124 REPORT— 1889. 



1,300 feet above the sea. The hills at the bottom end of the valley are 

 mamillated. The slopes are gentle. 



This valley is recent, and conclusive evidence of a former lake exists 

 •which had a large area. Boulder clay none ; local clay and loam, an 

 ample supply. Coarse gravel in the centre of the valley at one place, 14 ft. 

 thick ; sand about 3 ft. thick ; both freshwater, and partially lacustrine. 

 A few pebbles. 



Area examined between 700 and 1,200 ft , Ordnance datum. 



I found in the Denshaw Valley a number of boulders at New Year's 

 Bridge, 940 ft. above sea-level. They averaged 2 ft. 6 in. xl ft. 9 in. 

 xl ft. 6 in., and consisted of syenites and diorites. I have found no 

 traces of striae on any of the boulders, which are all rounded except one 

 or two. I found no isolated boulders. 



Notes. — This valley is carved in the Third Grits of the Millstone Grit 

 series. 



The hills rise to an elevation of 1,500 to 1,G00 ft. above sea-level. 

 The valley in the main is deep and tortuous, and the hills mostly saddle- 

 backed. 



Vegetation dwarfish and scanty ; very few trees exist ; the winds are 

 too strong, and the climatic conditions generally are too severe for tree- 

 growth ; besides, the soil is scanty and wet. 



Boulder clay is absent above the 850 ft.. Ordnance datum. Gravel is 

 also absent, and no sand worth the name is met with. Pebbles are few. 

 Valley alluvium coarse and scanty. The Yoredale shales crop out at 

 Rag Stones and Readycon Dean ; at the latter places the shales are very 

 carbonaceous and much-faulted. 



Area examined between the 850 and 1,268 ft. Ordnance datum.
