Now for something a little different. From Friday's hike in the Jura mountains at "La Givrine" stopped for some hot coffee at a chalet and thought to snap a photo of my adopted homeland's flag.

macguru212 posted a lovely photo of an erratic in Central Park.

Here is something that puzzled the founders of the study of geology. Common sense tells us that in stratified rocks the oldest rock is at the bottom and the youngest lies at the top. So what is going on here?

The old grey schist, approx 1000 million years old, is on top of the young white limestone, about 500 million years difference.

the answer: Moine Thrust at Knockan Crag

Land masses flip over, slide, etc... to see these processes in action (from a safe distance!!)

Right into the early 1960s, geologists who advanced the Continental Drift/Tectonic Plate theories were belittled as crackpots and wingnuts. The science was settled and the Shrunken Apple Theory was the only politically acceptable scientific view.

Interesting you say that, I was taught about tectonic thrust, and particularly the Moine thrust, at primary school in the 1960s. It is when you see it close up that your brain goes ‘huh?’. Wonderful stuff.

I think it was around 1962 that the evidence became so overwhelming that the current view started to become generally accepted at the academic level. Mid 50s on most working geologists were convinced their text books were in error.

I had a Physics 101 prof back in 1967 who would have gone absolutely Vesuvial had anyone uttered the phrase 'settled science' in one of his classes. To put it another way 'Settled Science' is one definition of an oxymoron.

All over the place but mostly Somewhere in England
So, today I thought I’d go a little off piste. In the middle of the Trafford Park industrial estate is all that remains of The Village, a company town moulded along the lines of the American capitalism worshipped by the British from the late 19th century through to today.

All that remains is mostly focussed on Third Avenue and includes a pub (open Tuesday through Frida), a pie shop, sandwich shops and even a very well regarded Burmese cafe. As far as I can tell, no one lives here so at the weekend it’s deserted, with everything closed.
