It was four days in total. The first day was at our headquarters in Keyworth where we were given an introduction to the geology of East Anglia, human evolution in the area and an overview of current coastal management issues. After this followed the nitty gritty of how you describe, interpret and classify Quaternary deposits according to the most recent British Standard.
Then it was off to Sunny Norfolk for the next three days to put all this into practice.
HappisburghWe started in Happisburgh, a site well known for its coastal erosion and somewhere we have monitored as part of our Slope Dynamics Project since 2001. The beach here is around 900 metres long and we were tasked with interpreting the entire cliff section to understand what's there and how it got there.

Over half of the bay had geology that looked like this, a nice gentle layer-cake affair:

But then the further south we went, the more complex it became. There was quite a bit of head-scratching, debate and even argument (!) about the palaeoenvironmental conditions (what the environment was like when the sediments were deposited).

East RuntonThe last morning was spent at East Runton where we were again asked to interpret the cliff section. This time, we were more confident and were able to use everything we had learned over the previous two days at Happisburgh. Again there was debate and a lot of drawing in the sand but we came to an agreed interpretation that I would like to tell you all about here but that would spoil it for those going on the course in the future! Instead, here are some pics...

So how exactly do you describe, interpret and classify Quaternary deposits?
