Geology rocks!

Basically, a place to post your favorite geology photos, anecdotes and finds (because there are a few of us 'rock nerds' on CF and I thought it would be funny). Geology is everywhere under our feet every day - I love it because it's this secret world of clues that no one knows (or probably cares) about. But it can tell us what happened to a particular place, and what lived there, millions and millions of years ago <3.

So last weekend (my 31st) I visited Hunstanton. I'd already got the cred a few years ago, but I heard there was a great beach for dogs where they are allowed all year round :D Apparently, the locals call the place 'Sunny Hunny'. It wasn't too sunny on our visit - we had to retreat to a cafe at one point as a mist rolled in off the sea!

The beach had some iconic, red and white stripy cliffs. They were laid down during the Cretaceous period (66-145 million years ago). Things were a bit more sunny in Hunstanton then, when it was below a warm, shallow sea (think balmy Egyptian coastline).

The top bit is chalk/limestone.
The middle is red chalk (turned red by the presence of iron).
The base layer is sandstone.

Some fossil fragments I found in the limestone layer - bits of shell, belemnite (a bit like cuttlefish) echinoid (sea urchin) and ammonite (like a giant floating snail).


He's my recreation of what Hunstanton looks like, then and now:

I would've replied to this earlier but I passed out with excitement after seeing the topic title.
I live near Torbay, which is a global Geopark so there's lots of interesting and unique geology.

There's lots of interesting formations and some amazing coastlines in Devon, here's some pictures from the internet as I don't have many:

I think Devon is known for its red sandstone?

Over half the house has now fallen with the rapidly retreating cliff.

Theres loads more, it really is an amazing coastline. If you haven't already, you geology nuts should really organise a trip along the Devon coast!

BTW Saffron is a great name for a dog!

One rock formation that's always fascinated me is the Wulingyuan mountains in China. Completely otherworldly!

I'm no geology expert, but just got back from Iceland and have a few nice geology pictures for you Sue!

Svartifoss (loving the rock columns)

Lower falls at Hengifoss (again, more amazing rock columns)

Hengifoss (nice layers of rock here)

Asbyrgi Canyon (really strange geological feature)

Some lovely ripples in the rock

And a nice little cave (presumably formed when the top surface was able to cool and solidify and the lava underneath kept flowing?)

You're right Sue, geology does rock!
