NOTES on the GLACIAL GEOLOGY of the COUNTRY 

 between LOFTUS and KETTLENESS. 



by Frank Elgee. 



In July, 1807, I made a glacial survey of the country 

 between Loftus and Kettleness. The result proved some- 

 what disappointing, very few striking features due to ice 

 action being met with. No opportunity to make a further 

 investigation of the area having since arisen, I propose in 

 this paper to bring together my observations with a view to 

 their being expanded at some future date. 



Generally speaking, the district is intersected by two main 

 valleys, that of Kilton Beck and its affluents and that of 

 Roxby and Easington Becks, with moderately elevated land 

 between them. A wide amphitheatre of hills sweeps around 

 Runswick Bay from Borrowby to Newton Mulgrave Moor, 

 and thence via Mickleby and Barnby to Goldsborough and 

 Lythe. 



The chief glacial deposit of the district is boulder clay, but 

 in some localities there are large spreads of gravel. One of 

 these covers the country to the south of Loftus as far as 

 Wapley, on the ridge dividing the eastern branch of Kilton 

 Beck from Roxby Beck. Wapley itself stands upon it. A 

 much larger spread occurs on Easington High and Roxby 

 Moors towards the boundary of the drift. On the former 

 moor, the ice margin is indicated by a line of fine gravelly 

 moraine, first described by Professor Kendall. Not far 

 from Tranmire, where a large overflow into Eskdale crosses 

 the North Cleveland watershed, the following section was 

 observed in a gravel pit : — 



Moor Soil. 



Fine gravel passing into coaly sand. 



Few inches of fine gravel. 



Fine sand at base. 



The erratics here were mostly small and of Cheviot Porphy- 

 rites. In one place there was a patch of ruddy boulder clay 

 near the surface.
