My dad was in North Africa during World War II, and I remember him telling me that in the desert it dropped so cold during the night that you’d hear rocks exploding: a form of freeze/thaw weathering. I can’t promise exploding rocks in Yorkshire but you can see the effects of the weather on even the toughest of our gritstones and sandstones.
On an old garden wall, I spotted this mushroom-shaped rock that looks like a miniature of one of the Brimham Rocks. Like them it has been sculpted by wind action.
