Last year, he found patch marks by the centre upright stones that were identified as the possible missing circle stones of the Inner Circle, therefore his contribution to the investigation of Stonehenge has been immense. Tim Daws picture of the post hole - EH would like to lose!! How much history is being lost through ignorance and propaganda?? Moreover, it supports my hypothesis, that they are all on the shoreline of the River Avon at about BCE. Furthermore, the fact that rivers in Britain were ten times larger in the past than today effected on not only the River Avon.

And not over the longer sea route, some archaeologist have considered.

Direct Boat route from Preseli to Stonehenge using the raise river levels of the Mesolithic This report also goes into great depth in the analysing of the Stone structure of the bluestones from other Preseli sites such as Carn Goedog, Cerrigmarchogion and Craig Talfynyydd, Carn Breseb, Carn Gyfrwy and finally Carn Alw areas.

Nevertheless, this should be no surprise to readers of the Craig Rhos-y-felin report is full of inconsistencies and logical inaccuracies as the layout of the site was never taken into consideration. The flooding of this area is well known to geologists as they have found sandy deposits are in the excavation sub-soil.

Craig Rhos-y-felin seen from space white circle Criag Rhos-y-felin as it would have looked as an island in the Mesolithic This misunderstanding of the past water levels has lead to Geologists misinterpreted the sediments or the past. Remembering this lack of distinction, we find in the report that an old river ran around this quarry as long ago as — BCE and possibly up to — BCE. This deposit is contemporary with the uppermost fill of a palaeochannel of the Brynberian stream that flowed past the northern tip of the outcrop.

Therefore, the obvious system of transport for these large newly quarried stones to their final destination at Stonehenge as we have seen in other countries with their own stone constructions like Egypt — was via a boat.

The 'enlarged stream' is more of a huge river - perfect to float a boat with a four-tonne bluestone down river to the Nevern Moreover, the site layout also gives a clear indication on when the stone was truly quarried.

There is a single monolith ready for transportation by the river on the east side of the site and the hearths which are clearly man-made are a few metres south of this monolith — where you would expect them. The problem for archaeologists is that these are Mesolithic hearths, and they're not just one but four hearths dating from — BCE; — BCE — BCE and finally — BCE and yet the report quite clearly states: Example of the kind of report that will be received from a commercial radiocarbon laboratory, including details of sample treatment and an estimated date BETA Analytic Radiocarbon samples Most organic materials are suitable for dating; the lower the carbon content, the larger the sample needs to be.

The Prehistory of Lums Pond: Radiocarbon samples were recovered from a variety of proveniences across the site. These included charcoal from concentrations within features; dispersed charcoal from arbitrary levels within features; dispersed charcoal from arbitrary stratigraphic levels not associated with features; and bulk soil samples from stratigraphic levels.

Without doubt, it has made the greatest single contribution to the development of archaeology since geologists and prehistorians escaped from the constraints of historical chronology in the nineteenth century. Single radiocarbon dates are relatively uninformative for constructing a chronology, whereas multiple dates help to achieve a closer approximation of the true date of the context from which samples were taken.


Bayesian statistics allow dates to be refined by taking account of additional information, such as other dates from the same site, or the sequence of dates from stratified contexts.

Uranium series dating The dating of rocks back to the Pre-Cambrian by measuring the proportions of uranium to lead or uranium to helium was possible because isotopes of uranium remain radioactive for such a long period. Fission-track dating This method involves counting microscopic tracks caused by fragments derived from fission of uranium in glassy minerals, whether geological or of human manufacture.

In practice the most useful samples come from zircon or obsidian, which was used extensively for making tools.
