The West Angle surveyed section which I have published before -- in slices -- has rather poor resolution, so here it is again. I hope it will be possible for future researchers of this site to blow this up and extract crucial information from it. Let's see how we get on........
Click to enlarge. This survey was done in the late 1960's during many visits, and completed in 1969.
You can see from this detailed section why david Bowen and others have made mistakes at this site. For a start, there is so much slumping on the face of the section that large parts of it are obscured for most of the time. Second, if you are just looking at some random sections where in situ sediments can be seen, you may well see the interglacial slits, clays and peat bed at a higher level than the reddish till, and may assume therefore that the till is older and the interglacial silts younger. Unless the sediment cliff face around point E is visible during your visit, you might not see the erosional contact between the till and the older deposits at all, and you might also miss the glacitectonic features including slabs of interglacial sediments caught up in the glacial sequence. If you only see a part of one of these slabs, again you might be misled into thinking that the till is oder than the silts and clays.
All in all, this is the most difficult Quaternary exposure in west Wales to plot and interpret; no wonder there has been endless confusion......
I think I have got it right, but I'm always prepared to be proved wrong if new evidence should be dug up!
