The Limeslade Erratic again

A strange little article has appeared in the  Quaternary Newsletter 164, pp 19 - 27 (February 2025) about the Ice Rafted Erratic spotted at Limeslade in South Wales.

A quick perusal reveals that the scientific argument rests on these two statements:

"In spite of the fact that far-travelled glacial erratics occur well above the coastal platforms on the south shore of the Bristol Channel, and up to an altitude of at least 80 m," (No reference given).

"more to the point they need to explain why ice from the Irish Sea Ice Stream can have left its traces at Kenn, Yew Tree Farm, Court Hill, Portishead Down and other localities up to c 80 m as without first filling the substantial lowland of the Somerset Levels"
(Gilbertson D.S. and Hawkins A.B. (1978). The Pleistocene Succession at Kenn, Somerset. Bulletin of the Geological Survey of Great Britain, 66, 41 pp).   

Unfortunately the G&H reference is outdated and there is no evidence for any glacial erratics naturally occurring much above sea level south of the Bristol Channel - see 
The Myth of Bristol Channel High-level Glacial Erratics   for details and references.

Without this myth the response is just a polemic that insults the intelligence of the readers of the QN.

As Willy wrote in Hal V, quoting Plato;"I did never know so full a voice issue from so empty a heart. But the saying is true: “The empty vessel makes the greatest sound.”


An imaginary scene but closer to the truth than the alternative theory
