Four crucial questions



Off the record, I've been chatting with a colleague about the key issues in the "bluestone transport debate" -- and he suggests that the following questions are all crucial.  He suggests that none of them have been answered, and I tend to agree with him.   Answers from archaeologists please.........

1.  If the bluestones at Stonehenge were revered or venerated to the extent that they were worth transporting at great cost across land and sea, why are there so many rock types, shapes and sizes represented in the bluestone assemblage, including many soft and flaky "rubbish" stones?

2.  If the bluestones were transported by human beings, why are there no stones in the orthostat group that have come from the north, east and south of Stonehenge?  Is it a pure coincidence that they have all come from the west, on a route known to have been followed by glacier ice?

3.  If the stones were carried by humans, how did the members of a Neolithic community centred on Salisbury Plain know of the existence of a supposedly “sacred mountain” in West Wales, and where is the evidence showing that they had the geological, geographical and navigational skills to locate it and exploit it?

4.  Why is it that other dolmens, standing stone settings and megalithic monuments dating from the British Neolithic are preferentially built with stones collected in the immediate vicinity?  Does this not suggest a “utilitarian” or pragmatic culture which had no interest in long-distance stone transport?

Mount Hood moraine


 An interesting photo of the jumbled moraine exposed on Mount Hood in the United States, in the Sandy Glacier cave system.  Notice the wide range of rock types represented and the manner in which, even here high on the mountain in the "wasting glacier" zone, there is substantial rounding of the boulders.  Some of this might have been achieved by meltwater, but for the most part we are talking here of the effects of true GLACIAL processes.

Ice Requiem

World of Ice

Here is my rather meditative video about glaciers and icy things generally. Enjoy! I'll try to embed it into the post....... http://youtu.be/xTBVp6Vz3Lw

Blood Falls


Since visitors to this blog enjoy a spot of the bizarre now and again, here is another for the collection -- Blood Falls, on the flank of the Taylor Glacier in Antarctica.

Apparently the red colouring comes from iron-rich water issuing from the glacier in an area of very high evaporation.  As the water evaporates the salts are concentrated, and they also become rust-coloured as a result of oxidation.  Very interesting......

A note on Blog Posts

After that glitsch related to my mail programme, all is now functioning as it should.  However, I noticed the other day that a lot of Anonymous messages are still coming in......... please note that such messages go straight into my rubbish bin, without any intervention from me.  I'm aware that some of these messages are bona fide ones, but 99% are spam, sent by automated systems that simply crawl the web for blog sites. 

So if you have anything to say, PLEASE say it, but with a name or pseudonym attached.  Thanks!  And a Happy New Year to all!
