Two papers uploaded today :
Constraining the Fremington Glaciolacustrine Clays: and its implications for the Irish Sea Ice extent.
and
A Case for Predominantly Fluvial and Periglacial Origins of the Fremington Clays, Devon
Finally I think I have sorted out a lot of misinformation about the Fremington Clays and the implications they have for how far and high the Irish Sea Ice overrode the Devon coast.
The clays are a small area of pure potters clay in the Taw estuary near Barnstaple. Some say they show a 100 m high glacier stormed ashore there. The evidence shows that there was just an ice/debris dam at the shoreline which was about 30 m high.
Why it is important for Stonehenge: the Glacial Transport theory needs a mighty wall of ice to reach Salisbury Plain.
Have a read – they are based on solid geological data not wishful thinking.
