  2. When I was a student the departmental SEM was a bank of machinery about 4m long 1m deep and up to 2m tall. That thing you’re using looks like a pretty anonymous computer.
    How much did it cost?


    Bo Freekin Ya!

    Some of you are familiar with Clovis culture that was wiped out (likely) by the event(s?) triggering the Younger Dryas. My belief, (as stated on here previously) is that Clovis people probably (IMO) originated in Europe.

    The Clovis point bears a marked similarity to Solutrean points, found in France and Spain. Clovis sites are most heavily located in the Chesapeake Bay/Tidewater region. Genetically, Haplogroup X has an interesting geographical distribution.

    But… many discount the idea of a European origin for Clovis, clinging to the Bearing Strait Land Bridge idea.

    Well… the clinging just got a bit more difficult.

    Ancient Virginia Flint Knife came from France

    “What’s more, chemical analysis carried out last year on a European-style stone knife found in Virginia back in 1971 revealed that it was made of French-originating flint. “


    So… a 19,000 year old knife, made from French originated material…

    It doesn’t prove my belief… but it is very interesting.

    • I am with you on this one Lurking. There have been land bridges and Ice bridges which have long gone. It doesn’t take a little thought that small family parties of Nomadic/ hunter gatherers would venture westwards following deer, seals, larger fish, any food to survive. A long and perilous journey may have been possible. A little thought that as the icecaps receded so animals, then humans followed. It was a day’s walk to cross from what is now the west coast of France to the south east coast of England.No one is sure about the route Via Scandinavia, Iceland, Greenland and then eastern coast of America I am sure that some others found east Coast of the North American continent well before Columbus did.
      This is a very interesting paper which suggests possibilities.

  4. Very cold here in NW England and a Northerly wind. Interesting our word for winter sounds very like the Icelandic word for wind. Most of Europe do not pronounce “W” as English do they sound it more like English “V”. Pronounce winter as Vinter and you almost have the Icelandic word Vindur = wind. “D” in Icelandic sounds a little hard like “T”.
    I think this is another word we have soaked up from the many Norse immigrants who settled here. probably wrong but I just love the English language and it’s roots in so many cultures.

  5. The SEM and TEM microscopes are amazing pieces of equipment. Your SEM is much smaller than I’m use to seeing. Do you have any ash images posted on your site? I have looked but cannot find any. We take microscopic pictures daily but of tissue components, so I’m interested to see something new.

    • They are here on the site…. but I am just now comming online and can’t dig up the direct link just yet due to my coffee deficiency. Give mme a few minutes.

    • Hello Histologistics! To view Spica´s images just click on any of the links in the post above (El Hierro, Etna, etc.) or choose from the “Microscopic images” menu in the header. 🙂

    • I have a few more images i never came around posting, due to lack of time. The ashes i collected and which were sent to me the last year were all very magnetic ( almost all originate from the Canary Islands).
      Those cannot go into the SEM, i am allowed to use, because they could contaminate the scope. In case you got new ( not magnetic) ashes on your hand, please send them over, then i can do new images.
