    About Gareth

    For those of you who are not geologists, a tuff is a volcanic rock, made up of solidified ash. Hence the pun as my blog title. Actually, my research...

    Happy New Year, and welcome to the first "Where on Google Earth" (WoGE) of 2011.  I was shocked to find out that my guess at WoGE #245 was correct, (Plymouth, Montserrat being the most post-apocalyptic looking place I could think of) so it is with great pleasure that I present WoGE #246.

    For those of you new to this, the rules are simple.  The winner is the first person to correctly guess where the picture below is from, and to post a comment with the location (name or latitude/longitude) and a brief description of the geology of the region.  The prize?  The chance to host WoGE #247 on your geoblog (and if you don't have a geoblog, the chance to start one up)!

    Hopefully this will not be too difficult, but I won't invoke the Schott Rule.  I particularly like the way half the photo is in winter, and the other half in summer.

    Happy hunting!


    When I click on the small screenshot above, it takes me to a "404" file not found error message. Can you check that out?

    Never mind -- now it's going to a new URL via Flickr, and that works fine. Sorry!

    Fixed.  It worked fine on the preview, when I actually posted it for real it failed...
    We're looking at the Chaîne des Puys volcanic field in France. 45.77 N 2.97 E. According to the Smithsonian Global Volcanism Program: "The Chaîne des Puys, prominent in the history of volcanology, form a N-S-trending chain of basaltic and trachytic cinder cones, basaltic maars, and trachytic lava domes in France's Massif Central that has been active into the Holocene. Construction of the present-day Chaîne des Puys began about 70,000 years before present (BP), and was largely completed by the beginning of the Holocene. Holocene eruptions constructed lava domes such as the Puy de Dôme, whose growth was accompanied by pyroclastic flows, cinder cones that fed lengthy lava flows, and maars. The latest well-documented activity took place about 6000 years BP near Besse-en-Chandesse and included the powerful explosions that formed the Lac Pavin maar. The dating of younger tephras has not yet been confirmed, and reports of historical eruptions as late as 1000 years BP have been discredited."

    Yes, spot on.  That was very quick.  Next time maybe I'll make it a little harder...
    Wow, we are moving faster than I can follow it ....

    I also should have followed more carrefully! Well done Anne!

    That one was answered in an hour.  Do you get a do-over or does it move on to another writer now?
    It moves on, until (if) I win again...
    Romain: that was your backyard.... ;-)

    Indeed Felix!
