I just looked at the rock of Gibraltar on the web, and it's more interesting than it looks. 

I like the clouds that hit the rock, and are forced upwards like in a chimney. I actually have found that in one other place, a mountain on Achill Island in the west of Ireland. It's a similar cliff, but nearly 1,000 ft higher, and when I reached the top (from the easy side) I was amazed to see clouds shooting up vertically into the air, right in front of me. 

But another interesting thing about the rock is that it's composed of ordinary-looking sedimentary layers, but they are upside down, with the youngest rocks below the older ones. It must have had some pretty vigorous folding in it's history.

This is interesting. I did not know about such cloud systems. 

Wow, I did not know of this at all, this is actually really cool, thanks for sharing!
