On the offchance that Mike may still have a laptop with him, and may take a glance at this blog, here is the message again. Let's treat it as an "open letter" since there's nothing particularly confidential in it. This is the message:

Re the current exposures at Rhosyfelin
Sorry to miss your talk this evening -- my wife needed the car, so I am confined to quarters. But on the way home before supper I looked in on the site, and now that you are digging on the valley floor proper it's looking very interesting indeed. In fact, I'd go so far as to say that it begins to look like a classic Pleistocene site, with a fascinating stratigraphic sequence which seems to stretch from the Late Devensian glaciation through to the Late Glacial and then the whole of the Holocene. So -- congratulations are in order.
CAN I PLEASE URGE YOU NOT TO FILL IN THIS EXCAVATION SITE UNTIL IT HAS BEEN LOOKED AT BY A QUALIFIED GEOMORPHOLOGIST? You may not want me to do it, given our rather obvious differences of opinion, but there are plenty of others who will know what they are looking at -- and if your partners from Dyfed Archaeology and the National Park and other specialists like Richard and Rob have any sense at all they will agree that a serious professional opinion is now vital. You may have discovered the sediments from Lake Brynberian, or something like it, and torrential fluvio-glacial deposits like the ones you have uncovered are very seldom seen in inland locations like this one. So you have till, rockfall debris, fluvio-glacial materials, and at least 2m of very interesting fine-grained sediments above, grading up into colluvium and modern soil. If there really was a Lake Brynberian in this neighbourhood, you should find laminated fine-grained sediments BENEATH the torrential fluvio-glacial boulders and gravels. So please keep going down, if you have the energy and the time, in order to see if they are there...........!
I might even suggest that this site should be designated and protected -- and on that basis it needs specialist assessment before the evidence disappears!
I'm copying this to some others with an interest in this site, in the hope that you can all come to a consensus on what to do next.
Best of luck with the rest of the dig.
All good wishes
Let's hope Mike and his colleagues are able to respond positively to this request, since I am now quite convinced of the great importance of this site for our understanding of Pleistocene landform development and chronology in West Wales.
