How interesting that my Substack post that just dropped this morning is all about...

Tuff!

There is a lot of it in the American west, so tuff is featured frequently in my posts.

I try so hard to be interested in rocks… and love their tales told well - thank you!

Really interesting. I lived in Ecuador for six years and the next volcanic eruption never seemed far off.

Whereas here in UK the last proper volcano was around 60 million years ago - it happened on the Island of Mull. There was one around 350 million years ago in the middle of Edinburgh... The volcanoes that give us the tuff rocks of Wales and the Lake District were back in the Ordovician Period, around 450 million years ago.

As it happens, I've got a nephew who lectures on this kind of thing at St Andrews. He has a special interest in Tephra.

Love the weird and wonderful patterns left in volcanic rocks - transforms them into works of art!

Yes that boulder from Bow Fell could go straight into a sculpture park
