Old slate workings, Llyn Peris

Backblipped.
Taken from a lay by on the main road up Llanberis pass. It was a toss-up between this and a photo of a serious ice cream dessert, but this won. I've sharpened this a little as it was taken using (experimentally) a waterproof case for the iPhone, so it was shot through a layer of plastic. Which has done remarkably little damage, considering.
