An Aeolian Pleistocene Deposit at Clevedon. 



By Edward Greenly, D.Sc, F.G.S. 



{Concluded from p. 376.) 



Other Localities. — Eight feet of loamy sand have been found in 

 Walton Park Hotel garden, and are banked against the cliffs about 

 330 yards south-west of Ladye Bay. Mr. G. E. Male has lately 

 found what he considers to be the same sands on the southern slopes 

 of Worle Hill at Weston-super-Mare. Beyond Yatton there is some 

 obscure stony sand in a gap of Cadbury Hill, near Cleve, and a trace 

 of sand on the summit which cannot have been derived from waste 

 of the limestones. No other signs of these deposits have yet been 

 detected in Somerset, so far as I am aware, away from the 

 Clevedon ridges, though traces of them may be looked for on the 

 southern slopes of the Mendip and other adjacent hills. 



In Geology in the Field (published by the Geologists' 

 Association), however, a short summary is given of certain 

 accumalations that are known in the Cotteswolds. At various levels 

 on the sides of those hills there are yellow quartzose sands, more or 

 less mixed with rock debris, and the sands, with which there are 

 occasional bands of clay, spread out on to tb e lower lands. Mammoth 

 and other vertebrates are found in these sands near Cheltenham, 

 and freshwater shells of living species near Stroud. Some of the 

 rock-fragments are slightly rolled, and when the formation is traced 

 northwards erratics begin to appear. I have not seen these deposits, 

 but they seem to resemble those of Clevedon in several particulars, 

 though with differences that might be expected some 35 to 45 miles 

 away to the north-east. Perhaps even the sands, loams, and rubble- 

 drifts of southern England may yield interesting parallels.^ 



The Age of the Deposits. 



Professor Eeynolds remarks that the probable presence of the 

 Arctic fox and the Norway lemming, with the character of the 

 voles, all point to a " very considerable antiquity " ; and Mr. Martin 

 Hinton regards the faima as not later than the Middle Pleistocene. 

 All the vertebrates, however, were found in the lowest of the 

 deposits, so that the loam, sand, and upper breccia must be some- 

 what later. The formation shows no sign whatever of marine 

 reassortment or marine erosion, but as it is not seen below 30 feet 



^ With regard to all the sections mentioned in this paper, I desire to point 

 out that 1 have not re -visited Clevedon since my return to North Wales ia 

 April, 1920.
