Most likely scratchings from a mechanical digger. The enthusiasm with which he turned his head convinced me that we (especially he) should be super-careful with sites of significance.<br /><br />Hey Kostas, go troll somewhere else for a while.

I present the...Apologies for banging on about this. I present the following example, to demonstrate the importance and relevance of detailed studies of Pleistocene sediments, and the sheer vandalism that their wholesale removal by mechanical excavator represents!<br /><br />In our cave dig on the south flank of the Mendip Hills, the following information was gleaned from detailed and careful study of one small boulder, and the sediment that it was buried in. <br /><br />The boulder consisted of a stalagmite covered by a later deposit of flowstone. Both were dated. The flowstone gave a date of 50-60ka the stalagmite it covered gave a date of 420-560ka. <br /><br />Study of the older stalagmite, showed that it had grown in an open fossil cave passage and had been broken off and transported along the currently full cave passage, by a vast volume of melt water, Its envelopment by the later flowstone showed that once the flood melt waters had subsided, the passage had remained open between c. 420ka until 50-60ka. With no further floods during subsequent glaciations!<br /><br />This suggests, that there was one catastrophic flood event in the Mendip Hills at around the time of, or prior to the Anglian glaciation but none between 420ka and the Devensian. <br /><br />Study of the sediments surrounding the boulder, showed that they are most probably a mud flow deposited during the Devensian. <br /><br />From particle size analysis of the sediments and measurement of the cross sectional area of the passage, it was possible to make fairly precise estimates of the volume and velocity of the water that deposited the various layers of post Devensian sediments.<br /><br />All this from a deposit of pleistocene sediment <1m2<br /><br />That is why I'm saying the wholesale removal of the unstudied sediments surrounding the pseudo orthostats by mechanical excavator, is nothing more than criminal vandalism!<br /><br /><br /><br /><br />Alex Geenoreply@blogger.comtag:blogger.com,1999:blog-1228690739485734684.post-80431054206374902662015-04-12T18:58:59.384+01:002015-04-12T18:58:59.384+01:00Chris; your comments are all very eloquent, but my...Chris; your comments are all very eloquent, but my main point is still valid.

Yes, but in a dig you have to go down to find out what;s below. All we can hope is that the sediments (including the rockfall debris, the till and the slope deposits) are accurately described and quantified. as I have said often, my big concern is the manner in which the fines have been preferentially removed, leaving behind the larger fragments (slabs and boulders) on the assumption that they were there before the fines arrived.

If a journal editor wants a controversial article published, he will ask the "right" referees, who can be counted upon to give positive reports and feedback. If he wants an article turned down, again he can find the "right" referees for that purpose. The effectiveness of peer review depends on the skill-set of the referees, and their inclinations!

No stream in it. The flood plain probably floods during periods of flood -- statement of the obvious! As far as the sediments in the dig site are concerned, dated organic materials will always be older than the sedimentary context in which they are found -- by days, week, years, decades, centuries, millennia. Depends how much recycling has been going on. The interpretation of dates for "dated layers" can be a rather sophisticated business.....

It is on a steepish slope down to a river valley. Again from memory, there is a small stream or culvert running some 20 metres parallel to the rock face which has become the centre of interest. I think it was dry when I noticed it, but it is very likely that a lot of water runs down this slope in the wet periods which are frequent here.<br /><br />The river itself is almost certain to flood the lower level of the dig regularly, although I have not seen it myself. Anyone curious about the biblical power of these little streams in wet weather should visit the museum at Cenarth a few miles away and view the photos.<br /><br />My point is that the sediments have been washing in and out of the dig site for thousands of years. When material for dating is found it will be amazing when the time of deposition at the site can be established with certainty.chris johnsonhttps://www.blogger.com/profile/16210890033354730381noreply@blogger.comtag:blogger.com,1999:blog-1228690739485734684.post-58257957408154426562015-04-11T17:52:39.748+01:002015-04-11T17:52:39.748+01:00Although as Brian says in his post;

Now having receded to just meters away from the Crag.<br /><br />But you make a valid point when you argue serious scientific study needs and should be made on Rhosyfelin. Why there hasn't (of the sort Brian has been strongly advocating for so long) raises many questions about the intent of the archeologists. If "truth" is what they seek, why not have such scientific studies and expert analysis?<br /><br />Sure, Dr Ixer has done an amassing job identifying the provenance of some rhyolite fragments found at Stonehenge. But such findings have been now serving the Archie's interests and not the interest of scientific truth. <br /><br />KostasConstantinos Ragazasnoreply@blogger.comtag:blogger.com,1999:blog-1228690739485734684.post-82853794143988797192015-04-11T13:55:05.541+01:002015-04-11T13:55:05.541+01:00I doubt anybody disputes the geomorphology on disp...I doubt anybody disputes the geomorphology on display at Rhosyfelin, or even that it is unremarkable. The unremarkable nature of the glacial action is probably why nobody did an extensive scientific study of it. <br /><br />The big question is whether people in the neolithic quarried stones or a stone from Rhosyfelin. In this respect the act of quarrying could cover a wide range of human interventions; the most basic would be to select and collect a single stone lying on the ground. Disproving such a hypothesis verges on the impossible.<br /><br />If there are fairies anywhere in Pembrokeshire then Rhosyfelin looks and feels like a perfect location - at least it did prior to the archaeologists arrival.chris johnsonhttps://www.blogger.com/profile/16210890033354730381noreply@blogger.comtag:blogger.com,1999:blog-1228690739485734684.post-53940539253528886462015-04-10T23:06:23.522+01:002015-04-10T23:06:23.522+01:00"So they sink or swim together"
