And the answer? You’ll have to read the blog for that one!!
Jebel Shams and the region around it was laid down during the mid- Permian era (about 275 million years ago), and there are the remains of the Tethy’s Sea Exotic at Jabal Kawr on the road up. As you walk into the Grand Canyon, you see the whole of the Jurassic and the whole Cretaceous sequence of rocks (72 – 200 million years). It’s a bit awesome when you realise how long its been there.
Just seven days later and I was flogging my weary bones into Cwm Clyd on Y Garn complete with full winter kit looking for some snow and ice. I realised that the geological epochs were as similar here, although maybe not as spectacularly defined as Jebel Shams. 542 million years ago, the development of North Wales (and the Cambrian Period which took its name from the Welsh region, Cambria) was beginning and the final creation of the Snowdonia landmass we now see was probably completed about 2.6 million years ago as the glaciers began their work of exquisitely sculpting the landscape.
So the answer to the question 275,000,000 + 7 = ??
542,000,000 of course.
Yes I know that’s tenuous. But that’s what a blog is. Much ado about nothing …
