Frozen

We set out for Ullapool, as we needed groceries.

The weather improved as we drove north, so we kept going and ended up at Assynt, where we ate our packed lunch.

I took this on our return, as we passed Knockan Crag. The 'Creag a' Chnocain' (crag of the small hill) as it known in Gaelic, is a line of cliffs 13 miles north of Ullapool. It is of great geological significance as the Moine Thrust is clearly visible here. A lengthy debate was held by prominent geologists about the fault line exposed here. The Moine schists are sat on top of Cambrian and Ordovician rocks such as Durness limestone, so some believed that the Moine had be younger.

In 1907, Ben Peach and John Horne discovered and subsequently wrote a paper on the subject. It explained the action of a 'thrust fault', the first to be discovered anywhere in the world. Due to tectonic action, the older rocks had moved 70km to the west and over the top of the younger rocks.

There's a trail that you can follow from the visitor's centre, along which the two rock bands are exposed. You can touch both bands and span millions of years and the views are breathtaking. Another interesting point to note is that most of these mountains would have been covered during the last ice age!! Only the tops of the highest would have been exposed.

Thank you all so much for the huge amount of stars and hearts during the last few days! My apologies if I've not managed to thank you individually :-)
