Stone
This is a picture taken a few minutes ago of my backyard wall, which like the rest of those in our terrace, is a stone wall;
But I couldn't resist adding this second as it is one of my favourite pictures - I love the 'abstractness' of it.
It shows the rock formation at the bottom of Onchan Head - and, as you can tell by the seawater in the hollows, it is the ground surface - so horizontal. And clearly those, now vertical, layers would have first been formed horizontally and upheaval has caused them to lie as they do. A friend who is a geologist explained to me that this particular stone is "an instance of contact metamorphism where an older sedementary rock (limestone, apparently, which can also be varved, or deposited in distinctive layers) is cooked by contact with an intrusive igneous body".

It is, isn't it? Definitely you need your sandals on to walk over it.
And I totally agree about that bit of rock - I have walked on it in my shoes, but it is not comfortable!
