Click here for a new blog giving information about the Geology section news of the Bristol Naturalists' Society.
Wednesday 21 October 2009 at 7:30, SH Reynolds Lecture Theatre, Ground Floor, Wills Building, Bristol University, Queens Road. Isobel Geddes (Wiltshire Geology Group)– 'The pre-historic landscape from Avebury to Stonehenge' In this talk Isobel will relate geology to the Stone Age, Bronze age and Iron Age monuments and burials of the Wiltshire downs. In the light of the fascinating Field Trip that many of you undertook just after Easter, this should be a very interesting talk. Please invite anyone you know who is interested in landscape (Coast addicts), archaeology (armchair Time Teamers included!), or palaeontology/anthropology (Alice Roberts fans), to come along too. I presume that those without enough time to watch TV will come along as usual.

I've just come back from the Columbia River area of Washingston State, where it is now established that a series of gigantic catastrophic floods at the end of the last Ice Age made the present landscape. Could such a phenomenon have formed the landscape around the M4 ?

What an interesting idea Ian. Have you tried looking at the two areas on Google Earth?
Hello! - No,I haveen't had time to look at Google Maps yet. But I'm told that this catastrophic flood theory accounts for the present English Channel and the North Sea. It seems that ripple marks and other flood features can still be made out on contour maps of the English Channel, tho' now they're covered by a hundred feet or more of sea water. I suspect the same effect formed the Bristol Channel, but that dredging for sand will have destroyed most of these features.
On a related matter, I've told several geologists of my theory that a tsunami caused the parting of the Red Sea, allowing the Israelites to escape the pursuing Egyptians. And then the giant wave appeared and swept Pharaoh's troops away. It is well known that the first sign of a Tsunami is that the sea has receded far out - much further than the normal low tide level. However the geologists to whom I've spoken have only expressed mild interest in my theory.
