Where on Google Earth #493

Bill led me far astray with his WoGE #492, which turned out to be a sheltered inlet on the Andaman Islands.

Leaving the tropics from now, here is some exposed rock:

As always, post a comment with latitude and longitude and write something about the (geologic/geographic/hydrographic) feature in the picture. If you win, you get to host the next one.
Previous WoGEs are collected by Felix on his blog and a KML file.

  1. Hint #1: It is not in Norway.

  2. Hint #2: ... but it HAS been.

  3. Do you need another hint? What kind of hint could be useful? If I say that this is on an island, will that help?

    Isle of Harris, Outer Hebrides, Scotland

    The Isle of Harris forms part of the Outer Hebrides. The islands themselves are chiefly comprised of Archean and Paleoproterozoic crystalline basement. This particular spot is located in the Langevat or South Harris shear zone perpendicular to the main fault trends in the larger Hebridean Terrane. This particular exposure shows the Paleoproterozoic South Harris metasediments, said to be "The largest and best preserved outcrops of metasediment in the Outer Hebrides.

    Interesting clue Ole, I liked it. It narrowed the field down to the former dependencies of Norway, and it was tough to find one that looked like it had something crystalline at surface. Sure enough, this part of Scotland was once a part of Norway, fascinating.

  5. The mountain in the center is composed of white anorthosite, which is a lot more common in western Norway - right where I live. Plans to open a megaquarry on Harris to produce aggregate for all of UK were stopped by the locals. Which in a way is good for Norway, one of our important exports is white anorthosite aggregare for roadworks. It makes the tarmac light grey instead of black, reducing accidents on dark rainy nights.

    The Outer Hebrides were called Suderøyane (the Southen Islands) when they were Norwegian possessions, which might say something about the Norse outlook on the world.

    Over to Gord!
