Where on Google Earth #227

A post by Anne JeffersonI just couldn’t resist the Where on Google Earth challenge this week (It is a lot more fun the grading or dealing with misbehaving laboratory equipment.) After passing off WoGE #225 to Chris of Science Wars, I couldn’t help but claim it back by identifying a very small chunk of Welsh coastline pictured in WoGE #226. I have to say that the British green landscape and stone walls are a big help in narrowing down what part of the world to search.

For those that haven’t played before, here’s a quick overview of the rules. First one to correctly identify the latitude and longitude of the center of the image AND say something about what makes this area geologically interesting…wins. The prize is getting to pick the next WoGE location and hosting it on your blog or picking a geoblogger to host it for you. If you’ve won WoGE in the past, you have to wait one hour before submitting your answer for each of your previous wins (the Schott Rule). If you don’t remember how many times you’ve won, you can look at Ron Schott’s kmz file.

The number on the middle of the scale bar says 3.42 km which corresponds to an eye altitude of ~12 km.

Posting time is 4:00 pm, US Eastern Standard Time.

Happy Hunting.

    50°35’N, 16°08′ Czech Republik, Adršpach-Teplice Rocks are an unusual set of sandstone formations covering 17 km² in northeastern Bohemia.

    In the Palaeozoic era, this area was a tectonic basin or depression. There were numerous lakes and swamps on the floor of the depression with lots of vegetation. The prehistoric rivers flowing down the neighbouring mountain ranges deposited layers of mud and sand on the floor burying the plants under them. In this way, the nearby deposits of black coal were formed. In the second half of the Mesozoic era, approx. 100 million years ago, a shallow seaway spread into the interior of what we now call Central Europe. On the bottom of this sea, mighty layers of sand were deposited. Their weight and various chemical processes connected individual grains together forming sandstone rock. As the seaway transgressed (advanced inland) over the region and retreated several times, different layers of different materials were deposited again and again over the older ones. This resulted in various composition and resistance of indivi dual layers.

    After this area was uplifted in the Tertiary period, the sea retreated for good. The weight of the mighty layers of the hoisted and exposed sandstones broke the seafloor layers into a great number of individual blocks that eroded with time. Only the most resistant parts of what was once the seafloor, the square-shaped sandstone blocks, have persisted. Nowadays they can be seen in this region in the form of various table mountains, buttes, uplifted plateaus and rock areas. Geologic faults and cracks in this area are perpendicular to each other stretching in the NW – SE and NE – SW directions.

  2. Hi Anne,
    The Location is 50°36’N, 16°8’E : Adršpach-Teplice Rocks in Czech Republic. A Cretaceous sandstone plateau. The plateau has been ‘cracked’ by the weight of upper layers. After these layers were being eroded various table mountains, buttes, uplifted plateaus and rock areas remain. A perfect area for rock climbers. I posted a larger version of this post 2 days ago. Looks like my comment didn’t make it, so I try it again.

  3. Congrats Felix on another WoGE win. Apologies that your first attempt at claiming the prize got lost in the spam filter.

    I first heard about the Adrspach area at the Geological Society of America meeting a few weeks ago. One of the talks in my session focused on the potential role of groundwater in enlarging these joints into the spectacular scenery they present today. For anyone unfamiliar with the area, I encourage you to check it out on Google Earth and look at the Panoramio photos.

  4. I think the problem is maybe on my side. I commented more or less the whole book about the place. Next time I try to make it short. Nice area by the way, I’m going to check it out next time I’m in the wider area.

    WOGE#228 is up.

    Pah! I knew it was Eastern Europe – I just couldn’t find the outcrop on Google Earth! 🙂 Nice work, Felix!
